Can Anyone Catch Khan Academy?
waderoush writes "Even as name-brand universities like MIT and Harvard rush to put more courses on the Web, they're vying with an explosion of new online learning resources like Coursera, Udacity, Udemy, Dabble, Skillshare, and, of course, Khan Academy. With 3,200 videos on YouTube and 4 million unique visitors a month, Sal Khan's increasingly entertaining creation is the competitor that traditional universities need to beat if they want to have a role in inspiring the next generation of leaders and thinkers. Lately Khan's organization has been snapping up some of YouTube's most creative educational-video producers, including 'Doodling in Math Class' creator Vi Hart and Smarthistory founders Beth Harris and Steven Zucker. Universities are investing millions in software for 'massive online open courses' or MOOCs, but unless they can figure out how to make their material fun as well as instructive, Khan may have an insurmountable lead."
The Chronicle of Higher Education has a related article about the above-mentioned Coursera, and how they plan to make money off of free courses. A contract the company signed with the University of Michigan suggests they aren't quite sure yet.

Universities: KHAAAAAAAAAN!!!!
How much weight does a Youtube degree carry in todays market?
Since when has education become a competition?
My Kindle just lit-up with an ad from this company. 2 online courses for Excel at $35 (instead of 200). I was tempted to click "buy" however I know nothing about this company. I don't just hand money to random corps.

Vidcon, they started Vidcon!!! DFTBA!
There have been good textbooks for centuries. Watching a video is not going to improve things much. Online quizzes don't make people brilliant.
The first reason the top universities are at the top is their research output.
And the reason undergraduates excel at those top universities is that they spend almost every day for several years in contact with the people and resources which make that research possible. They go to tutorials. They chat through problems. They do extended lab work. They write extended pieces of work which are marked carefully by experts who can provide interactive feedback.
The Open University, the pioneering distance education factility in the UK which has several hundred thousand part-time and FTE students, has since 1969 provided more than all these supposedly "new" online education providers: custom textbooks tailored for learning with worked problems; a tutor who will mark your work and who you can contact whenever you want when you have a problem; several face-to-face tutorials throughout the year; possibly one or more residential schools; etc. Exams are all done in exam centres under exam conditions. Even then, it cannot hope to match the best red brick universities.
Khan knows how to market itself. It gives an opportunity to those dilettantes who don't know where else to find the information, online or offline. But it won't produce a new generation of leaders / top thinkers.
I've been buying their product since the 90s when they were called "The Great Teachers" company. I took advantage of their once or twice-a-year sales to clear the warehouse. A customer can buy an entire course (~50 hours) for about the same cost as a month of cable. I learned more about history, language, philosophy from those audiocassettes than 5 years of actual college.

This is the only Khan I like on YouTube...
Khaaaaan!!!!
It really all comes down to this. Kahn Academy is non-profit, and is more interested in the public good. Everybody else that wants to get on this bandwagon simply can't compete with this, because they want money, and lots of it. Nobody else will be able to stop them.
There's a lot of stuff being offered by traditional universities which is way above Khan's level. Khan is great for an introduction, and even a bit more, but that is all. For example, take a look at Stanford's Convex Optimization course: http://www.youtube.com/watch?v=McLq1hEq3UY
Khan doesn't offer anything close to that. There's plenty of room for competitors to grow.
The model of education used in the IS for the last 100 years or so is no longer sufficient. Online courses will be part of whatever the new system will be, but only a part.

Khan Academy is a great resource, but it's far from a perfect substitute if one want to accomplish deep learning. The fact is that there is a LOT of free and very helpful tutorial learning material on the Internet. Khan has caught a lot of interest because of the sheer scale that Sal Khan accomplished on his own. I think it's a great tool, but is becoming quite overrated in terms of what we know from those who teach face-to-face, and learning science.
Here are some valid criticisms of Khan Academy. http://chronicle.com/blognetwork/castingoutnines/2012/07/03/the-trouble-with-khan-academy/?cid=wc&utm_source=wc&utm_medium=en
http://fnoschese.wordpress.com/2011/03/17/khan-academy-and-the-effectiveness-of-science-videos/
In sum, Khan Academy is NOT a revolution in learning; it's a tool that many will use to help revolutionize education.
Khan Academy targets a wider audience than the others that are mentioned. Most of the others are aimed at university level education. For example, Coursera is mostly undergraduate courses like Algorithms and Cryptology. Udacity has some machine learning car. A lot of these are also tech based and/or programming based.
Meanwhile, Khan Academy offers everything from elementary Algebra and Geometry to Calculus and Differential Equations. So they reach the whole k-12 audience which the others will not reach. That isn't necessarily a bad thing, it's just a different product. I hope they don't water down Coursera because it's good at what it does: free undergraduate level courses. I don't want it to spend time doing 8th grade Geometry, Khan does that already!
On commercial television the length of programming between commercials is 5 to 13 minutes. I feel that may be more platable that the monolithic standard 50-minute lecture. But then too many modern professors may insert a click-quiz every 5-13 minutes to reinforce the material they had just delivered. Khan segments may work better for your hyperactive, multi-tasking kid.
Just recruit top dog professors willing to make the material with skilled programmers to make an interactive web app education platform. When a branch of education gets funding, allocate the resources appropriately and run the whole site free, integrate it with Wikipedia. Make some Facebook app to show an academic profile with badges and the like.
Having done a normal university course, a couple of decades ago, and now having experienced normal distance learning, where there is no interaction with other students, some with limited interaction, and some with a lot, I am totally convinced of the value of student contact with other students as a necessary element for really effective learning. Similarly the opportunity to challenge a lecturer over an issue is totally lacking in the Khan model; whilst that works to some extent for purely technical subjects, even there robust seminars are a useful adjunct to pure lectures. And it's this area where Khan will fall down; it's good as a means of transmitting knowledge from the lecturer to the notebook of the student - but education should be more than that. And it's that second element that costs the money to provide.
school should not be about makeing money covering costs and yes paying people good pay (not CEO pay) is ok.
But some places take that makeing money way to far with jacking up credits needed to pass, Fees, Forced meal plans and foreced room and board fees.
Khan's lectures are simple, accurate, and highly valuable. However, how much does one learn from passively watching great lectures which ignore a student's missteps and false presumptions? This Veritasum video on Khan's videos demonstrates the effectiveness, or rather ineffectiveness, of at least some kinds of video learning. (And yes, the irony of using a video to teach the ineffectivenss of educational videos will not be lost on anyone.)
more trades like systems is needed and less class room time with more hands on parts.
So part of issues is the ties to past where there is too much put into a 4 year degree skipping over the more focused trades / tech school learning there it should be not tied to a degree plan I think that some of the lack of respect does come from them trying to be 2 or 4 year degree places when they should really be trades based and offer classes on a 'Badges' like system.
Also a other down side of putting too much into a 4 year degree is that people going trades / tech schools can get locked out of some IT internships that are tied to the past system.
A Badges system is better than having continuing education be just masters, phd, Ect and are not only big time sinks they are also geared towards to being a teacher.
We have places like tribeca flashpoint but it is only a 2 year school but I have seen Film & Broadcast, Recording Arts, Animation & Visual Effects jobs that want a 4 year degree.
Also a other down side of putting too much into a 4 year degree is that people going trades / tech schools can get locked out of some IT internships that are tied to the past system.
We don’t need factory’s full of Forman / designers and we also need the Forman to be able to jump in and do the job from time to time as well. CS is kind of like that you are training people to be designers but they mostly don’t get the skills needed do the work on the stuff they are designing and we also need people with the skills to do the work and not so much to be a designer. Not that best analogy. A quick car analogy can be you are trading car mechanic to be an car designer / car engineer and in the clases you don’t even touch the insides a real car or even the tools used in a car shop.
"Fair enough, but in its essence, teaching is a performance art." - Amy Farrah Fowler
"Powers. I have them."
Trade schools / Tech schools should be there as well and they are more then just a some vidoes on line but they don't really fall into a degrees plan that well and there lot's of NON degree IT classes out there as well.
Can Anyone Catch Khan Academy?
Anyone? No. Someone? Probability would say "yes".
Universities are investing millions in software for 'massive online open courses' or MOOCs, but unless they can figure out how to make their material fun as well as instructive, Khan may have an insurmountable lead.
What a load of crap. I love Khan's materials, but not because they are fun, but because they are valuable. Plus, I had plenty of college professors that made their lectures fun. And I had classes that were some of the most imporant in my education, and I know the subject and delivery weren't fun. Fun is not an intrinsic property of good education.
Edutainment != education. Such is the state of our sorry ZOMG-Kardashian society.
Also there is pretention in the quoted text that colleges are having a hard time producing instructive online material. Seriously, have they never seen a Stanford/MIT online lecture? There are many universities out there providing grad-level education online with success.
Another thing that people misconstrue (and not a criticism of Khan's videos, but of the fanboys who do) is that Khan's videos are nice to watch because... gasp, they are, in general, relatively shorter than a full-blown lecture. A 90-minute long video lecture will bore you down no matter how "fun" the instructor is. Specially if the material is dense. Or try a 3 hour video lecture. You'll be crawling off the walls even if it is performed by your favorite professor (I know because I've had to take those lectures @ WPI.)
1. If Google were to decide to put its might behind Udacity (which is really fine material btw), wouldn't anyone think that it would pass over Khan Academy? Ergo, the title of this story is an oxymoron like no other.
2. Universities will adapt, prices will go down. They won't get replaced by them, in particular when it comes to research. What I see here is that these private enterprises will accelerate adoption of online media by brick-n-mortar schools (which has been occuring since before Khan came into the picture.)
This is not to take anything away from Khan's marvelous work. But for Christ' sake, don't treat it like the second coming holding the holy grail while riding a silver bullet.
plumbers and electricians don't have degrees they have Apprenticeships and trade schools (and you don't need to sit 4 years in a class room) now other fields like IT need something like this.
and the traditional University projects. likely are stuff that you will not see in the real work place and even then CS IS NOT IT!
I have seen lot's of IT jobs (desktop / admin / network) that want a cs degree then CS is more on the high level theory side of things and is more for doing programming work.
CrashCourse, the wonderful Youtube channel offering a history and biology course hosted by John and Hank Green!
and then you need to stop passing over people without a degree and give them a interview.
Any ways saying windows 2008 class , windows 7 class, ECT is a lot better then IT degree at X school.
I have yet to see any major university offering a CS Bachelors degree online.
It is nice to see Universities putting up free classes, but when are they going to start putting up material to obtain a full Bachelors degree (free or pay)?
It is the notion that someone will come along and take what Khan has done and make it a real substitute for traditional in class learning. Khan has taken a very altruistic approach to learning. He believes that it should be free to anyone that wants it. American universities, especially private universities, are most definitely in it to make money. Yes, they want to educate people but make no mistake - they want to bring in as much cash as they can. Look no further than college sports for evidence of that. I'm not saying this is necessarily a bad thing but it's at odds with Khan's stated approach to education. What the universities really fear is someone coming along that has a profit mindset and improving what Khan has done to the extent that it becomes a compelling alternative to traditional in class education. And if that alternative all of a sudden gets widespread acceptance in the business community as a valid degree on par with the in class degree the universities will be in a world of hurt. That's why they are all jumping into the online realm. They need to have some kind of offering out there just in case. Just as an aside, I have been working in the IT field for a long time and the best programmer I ever worked with had an English degree. The next best had a math degree. The next best didn't have any degree at all - completely self taught. I'm not saying that a CompSci degree is worthless but I have worked with an awful lot of people without one that were every bit as good as people with one. As more people with online degrees get into management I think you'll see the acceptance online degrees continue to grow.
Isn't this the last guy in Mortal Kombat?
well the old formal education system is not good for IT and it's time for them to look at new ideas and non formal class settings.
life skills degree what the difference you are just useing it to get to a real person and why should some with a underwater basket weaving degree get a pass over some with no degree and lot's of real work skills
IT requires a technical degree generally, not a four-year education. I don't see how it applies in this context.
college for all and the one size fit's all ideas = what we are seeing today in Universities.
Yes do need some post high school learning but we are going about it in not the right way.
Not all people are cut out for college and not all courses plans / classes are at the college level and other stuff is just fluff and filler.
Why does art history or hobby craft stuff at the universities level? Why do some schools still have required PE classes and swim tests?
there should be a GED for universities then.
But a drivers has a road test part to it and a test based on real driving.
But the minimum standards for say IT should be about doing the job and CS does not prove that but other IT classes do.
that is what continuing education is for so you take that windows 7 / windows 2008 class. And that can be done quicker and cheap then getting an degree.
Any ways what is better focused continuing education or 2 more years taking a full load of degree classes.
But lot's of IT jobs want a four-year education and passover people with real skills or people who took classes that don't fall into a 4 year four-year education system.
The four-year education comes with a LOT of filler that is not needed.
are 2-3 year core only degrees a good way to go?
The old ideas of being well rounded is moving to the nice to have part and why should you pay $20,000+ a year to lean art history and music when you don't want to get into them but are forced to take classes to just to fill credits?
There are a lot of reasons to be physically present at a "brick and mortar" university with an instsructor in the room with you.
To the extent that universities want to break from this model, it isn't about education at all. It isn't even about making an education cheaper; it's about extracting money from suckers.
So, good for Khan Academy for doing what they're doing and giving it away for free. All the bottom feeders (including Bill Gates) who want to charge money for this stuff have nothing useful to offer and are just trying to game the system in one or another way for a buck.
The good and new comes from no quarter where it is looked for, and is always something different from what is expected.
There's no accounting for bad hiring practices. We can imagine a hundred scenarios where employers do stupid things. I'm merely talking about employer's acting reasonably. A four-year degree is generally overkill for IT. Employers who fail to realize that are the ones at fault, not the candidates or the program they went through.
He talked about some of his great teachers in the past and some of the historical greats like Isaac Newton, what if they had made videos? A one time effort and it would affect generations far into the future by giving them access to these poeple.
It's not just IT I have seen broadcast and media jobs wanting them as well and you have Digital Media Academys that tech the needed skills and have lot's more hands on work then the older colleges.
Yes I have seen a a master control (TV) job wanting a four-year degree in communications. Now what does communications in college is about studies integrates aspects of both social sciences and the humanities.
Social sciences and the humanities don't help you run the tech side of master control but the classes at Digital Media Academy likely put in a real master control room and it not like there is 0 Social sciences and the humanities at a tech school
Also it comes to Animation and Graphic Design jobs that also want four-year degrees what does the history of art help you in using industry-standard hardware and software and producing a wide range of polished designs, from advertisements to package designs to websites and user interfaces.
designs to websites and user interfaces is very much on the tech side of things.
It sounds like this is an entirely unrelated issue pertaining to unrealistic ideas of what skills are required of candidates. Even in jobs that legitimately ask candidates to have a four-year degree in Computer Science, you still run into unrealistic requirements, such as having 10 years experience in a language that has only been around for 7, or asking that the candidate be an expert in dozens of languages, only a few of which they will ever actually use.
That's a separate issue, and while I do agree it's a problem, I don't see the pertinence, nor am I interested in discussing it further. Sorry.
Free online course material is not supposed to be a competitive market.
And I doubt that the people at MIT are really coming up with strategies to crush their "competition".
Troll is not a replacement for I disagree.
The problem is that most of today's fields of work are hard enough that the easy stuff has been done. We don't need biologists who know biology. We need biologists who know philosophy. We need ecologists who know physics. We need geneticists who know algorithms.
If you wanna skip art history fine, but the guy next to you who did take it just might have learned something that gives him an edge.
Steve Jobs took a lot of his inspiration from caligraphy crissakes.
Being well-rounded is more important than it EVER HAS BEEN. The interesting things are at the intersections between disciplines. If you want a "core-curriculum" education, go to a vocational school. Universities are NOT HERE to train you for a job. They are here to train you to think.
Intuitively, I gave up oin Khan when he toadied up to Mister Softie.
If you think using a free resource demonstrates value then w3schools.com is what everyone has catch. According to Alexa.com their traffic is 40 times greater than Khan Academy. In fact, w3schools.com has more traffic than khanacademy.com, codeacademy.com, udacity.com, coursera.com, and udemy.com combined.
Let's get real people. This is just dumb.
Khan needs better computer science courses. Their current selection is a joke.
What's your problem? The problem isn't the schools the problem is that you're anti-intellectual. There are no filler classes in a four year degree unless you choose to take them. Every school I've ever been to permitted me to fill those requirements in multiple ways, the smart folks went to their advisers and chose things that would be in some way useful in the future. More likely, what happens is that people are too obstinate to recognize what an opportunity those courses are. _Any_ course can be a filler course if you're not taking them seriously. Those interdisciplinary courses that you're bitching about are the ones that ultimately determine whether or not you're educated.
Being trained is fine, but don't pretend like a technical certification is as good as a degree as it's not.
http://www.post-scarcity-princeton.com/ ... Capitalism is often it seems all about cost cutting. Why do people have such a hard time thinking about what happens as costs approach zero, even for improvements in quality? Or why do economists have a hard time understanding that many conventional economic equations may produce infinities as costs trend towards zero? ... Here is one approach to "reboot" Princeton for a post-scarcity world. This is just an example. No doubt the creative minds on campus can come up with better proposals once they turn their attention to the matter. Should these be followed, it's a lot more likely I might encourage my own child to apply in a dozen years or so. ..."
From the essay I wrote four years ago: "... We are witnessing a historic end to scarcity of many things (maybe not all, but enough to be a new global Renaissance). But is Princeton University helping prepare either students or the rest of society for these changes? Or is it instead an institution under stress, crashing into these trends instead of moving with them? Or is it perhaps conflicted in how it sees itself and its future, and so trying to do both these conflicting approaches at once?
A 21st century issue: the irony of technologies of abundance in the hands of those still thinking in terms of scarcity.
3200? That's nothing! http://www.youtube.com/user/nptelhrd has 9935 technical lectures from all seven Indian Institutes of Technology and Indian Institute of Science, Bangalore.
0x or or snor perron?!
Right and that's a completely different issue. The practice ought to be illegal as it has a tendency to discriminate against applicants that don't know that they don't really need those requirements to apply. If they're asking for a BS, an AS is probably fine, if they want an MS a BS is probably fine and if they want 10 years 2.5 is probably fine. With 5 years you probably don't need more than a year of experience.
Why employers are permitted to publish fraudulent ads is beyond me. But it keeps the most useless people employed in HR, which is I guess something.

I had the opportunity to develop drivers and work for platforms where the hardware is exposed, Nvidia, ATI, Wii and PowerVR.
The truth is, such cards are pretty much a mess and the hardware interfaces are quite complex, because the hardware is designed around the drivers, and the drivers are designed around the APIs. At many points, it's amazing how drivers make up missing functionality in the hardware. The opposite is also truth, the hardware is designed to operate much faster if the drivers send the data in a certain, specific way, (than even with the full hardware register set published it's impossible to know)
This is why opensource drivers usually suck compared to the commercial ones and i don't see much hope of it changing. I many times read the noveau source code and compare it to actual driver code (or fully docummented hardware) and it's pretty fun how so much of it is guesswork and how little changes could boost the performance enormously
. If nvidia, for example, was more open they could easily give a hand to the noveau team without compromising trade secrets, but that would definitely expose their band-aided hardware hacks and quirks, so I guess that's why they remain silent
We don't need biologists who know biology.
That is precisely what we need. They don't need to know philosophy, they need to be good at their jobs!
There is no money in free except to sell it to advertisers who are effectively gamblers.
There' is money in low-cost if you keep your overhead low enough however. The established educational players have fought this for years b.c their overhead is non-negotiable and built into their business model. I know, I tried pre -year 2000 to get a university to offer its courses online and paid the price for my foolishness. They'll resist this to the death not because it's undoable or a bad idea, but because it's the end of everything they have.
The way all this is going to shake down is as follows: new players will create the courses and other new players will assemble an accreditation system that involves people's identities and establishing the veracity of their academic achievement. The universities seeing the writing on the wall will be late and very reluctant players to the game, offering up shit like a "Harvard Online Degree" say, representing some sort of lesser degree than the "real thing" .. that sort of crap. Anything else forces them to cannibalize their base offering, which they can't do.
In the end , really good people will come out of the independent virtual university system and that will be when it all comes tumbling down for the universities. University ratings are effectively a battle for bright minds, since universities don't actually know how to create smart people, but rather succeed by culling smart people from the general population, then claiming them as their own, as their alumni.
When that's gone, when that starts to crack, they're fucked.
Tuition is a bubble, as is student loan debt. It's a price divorced from any kind of underlying reality of the buyer's ability to pay or even benefit bestowed . New entrants in education will mercilessly leverage the holy fuck out of this basic economic fact while the established universities sit on the sidelines diddling their clits and blaming all their woes on tenure. .
Low cost , virtually free education combined with independent proof of student identity and achievement combined with the inability of universities to move in the same direction and remain solvent will, in the end, force universities to turn to the Feds for their continued existence. Their argument will be "our labs, our basic research is something our nation can't be without" , and they'll be right.
At that point a new deal will be struck- free universal education in exchange for higher taxes and continued existence of universities. That will lead to more culture war since conservatives see universities as the Great Satan of Liberalism and are sure as shit not going to pay taxes to keep them going.
Finally, just at this time, this issue will crash head on with global warming as the reality of what the universities foretold becomes indisputable
At this time, the country will have a choice to make- we can do what every other nation does and publicly fund the universities and their essential work or we can lose that function entirely. Either we consciously and publicly acknowledge that
1) supporting science and teaching reality based thinking is a basic necessity like food clothing and shelter and lifelong education a basic right and in fact duty of citizens and
2) continued technological and social progress are the primary and proper functions of society
or we cease to be able to pretend that we're world leaders, opting to devolve into a religio-based backwater , a fundamentalist Conservistan whose bright people have left or are leaving and whose best days are long behind it.
Science will inevitably be proved to have spoken the prophetic truth about what people will realize is the greatest threat to human civilization ever, global warming and the regressive, reality denying conservative movement will wither away faster than a river birch in a drought.
America will finally be of a mind to once and for all reject the dark s
Am I the only one who finds Khan's teaching style boring and superficial? He doesn't incite you to think mathematically. The pace is extremely slow. In videos it shouldn't be necessary to slow everything down, because you can always rewind, or pause to digest, or read up on something and come back. Maybe he's popular because he's good at making people think they understand, but what do they really learn?
The online uni brigade are trying to differentiate themselves with some kind of "qualification" at the end (a mostly worthless certificate at this stage).
Kahn academy is trying to educate purely for learning purposes (no recognition for knowledge gained).
Evidence that they can co-exist: ... sorry couldn't resist that last bit
I recently enrolled in a Udacity course for fun. The pre-req learning list was a bunch of kahn videos
as opposed to: http://www.youtube.com/watch?v=qXNqEURmKtA&feature=related
From what I have seen the exact degree one has often does not matter in many jobs, but you have to have something. Now, there are surly fields like medicine or engineering where one had better have the correct degree, but oftentimes the degree is just an indication that an individual is smart and can work hard, or they wouldn't have made it through college. This is not to say at all that people without degrees are not smart or dedicated, but they have to prove it some other way.
This is the problem with Khan Academy and all other non-degree granting self-education. They may teach topics well, but employers will have to find another way to test for your skills and work ethic, and when there are 100 applicants for 1 job the easiest thing to do is to filter for only people with college degrees.
All this said, Khan Academy really shines as a supplement to regular coursework. I am currently in college and have many friends who credit Khan Academy more than their profs. for helping them pass some classes.
Man...I step away from /. for a few months and return to a firefight. Listen up peeps...any and all form of education is important. Always keep in mind that people learn in different ways and that no single method of teaching is correct. Having attended a higher education institution, I can honestly say that there were times when something like this would have helped me immensely unlike the tenure dullard that was teaching the course. All of these institutions understand that they need to modify how they reach people interested in learning and obviously, their hope is to get you to come to THEIR institution.
Here in the US, we have done a wonderful job of rewarding the WRONG individuals and have not stressed education enough. Just take a look at the majority of TV shows lately...or sports figures. The number of these individuals that actually have an education and can speak intelligently is in the single digits. Not exactly the role models I want my children to look up to. Also, WAAAY too much continues to be placed on personal gain and wealth. So what if I have to stab you in the back, twist the knife, get out the machete and hack you to bits. At least *I* get ahead!...again, NOT the message I want my children to go out into the world thinking.
Education in all of its forms and methods are a Good Thing (tm). If the Khan Academy is the bar that everyone else has to measure up to, then so be it. It's a better alternative to the idiot box and another spin-off of CSI:Whateverthehell or Jersey Shore.
"Klaatu, verada, necktie!" -Ash
Dover is the stodgy old tortise who has been providing university-level math books for many decades at really cheap prices. Anyone can get educated using them. Khan is new, and flashy, but it's not like this was impossible before someone hyped it on the Internet.
Now you can fall asleep watching online lectures online, instead of attending them in person. Personally, I tend to nod off after about four minutes .. :)
The Open University has been available on television since at least 1969 and online at OpenLearn since 2006.

On the other hand, does matter. I would chastize someone for using 'your' not because they misspelled a spoken contraction but for using 'are', a form of to be. Makes you much more prone to talking nonsense.
