Spolsky's Software Q-and-A Site
guzzibill writes "Joel Spolsky has announced the beta release of Stack Overflow, intended to be a high-quality source of answers to software questions. Post a software question and watch the answers flow in. Popularity voting is very much woven into the site, where both questions and answers can be edited for clarity and voted up or down for correctness. Correctly posed questions and insightful answers float to the top. This site has reached critical mass." From Joel's description, he was envisioning a source of technical Q&A about programming. So far, many of the questions are broader and less technical, such as advice on the best book about software development. It will be interesting to see where the community that's forming takes it.
I've been using it for the past day or so, and although there are lots of decent questions, there are also a lot of people who post things that could easily be answered by with Google or RTFM, a lot of students posting homework questions (and getting answers!), and a lot of people posting bad code as answers. Time will tell whether they can build a community that can resolve these problems, but in my experience, the quality of these types of communities only goes down.

I think the most interesting thing about StackOverFlow is the reputation system. The more good questions and answer you create, the more power you get. From the FAQ:
Questions and answers can be rated, so that helps. As your rank increases (by posing good questions and helpful answers) your abilities on the site increase, up to the point where you virtually become a moderator. The algorithm for determining this may need some tweaking--right now, you need 6000 points to achieve the highest rank, and you get 10 points for a being modded up (losing 2 for being modded down.) If it's anything like other moderation systems, a bunch of people will get together to mod each others questions and answers up enough to become Stack Overflow gods.
The site is now out of beta. I was one of the original beta testers and I can attest that this application is truly revolutionary from the other BBS/Q&A sites that exist out there. First off, it is totally free. Secondly, all of the stupid answers and questions get voted down and disappear very quickly. (Like the guy wanting you to "send me teh codez for class assignment"). Thirdly, the user interface is superb for a web-based app as well as the search functionality. It takes all of the new fangled web features and combines them into this site. You can even get 'badges' sort of like slashdot karma. Way to go Jeff and Joel!
I've used Devshed for more than a decade. Usually I've been able to at least find people to point me in the right direction. Okay, layout and ads are a pain, but it's free.

I asked a moderately hard Perl question (there's a problem in Date::Manip that seems to be configuration dependent), and within two minutes, I had a wrong answer. No useful replies yet.
If Google is ranking them highly then they are either paying ExpertExchange for robot access (doubt it) or ExpertExchange is engaging in a form of cloaking (i.e. pay or you cannot see what the search engine saw without paying), which I thought the Google page rank algorithm penalized because it is frequently a sign of black-hat SEO. I agree that subscription only sites should be identified as such in the Google search results, although most of us know by now that ExpertExchange charges for answers and avoid it for that reason anyway. I don't dispute their right to charge for answers, but why should I pay them when I can usually find the same information for free unless it is very specific or obscure?
