Kazaa Usability Study

Anonymous Coward writes "We have just finished a study that shows how user interface design flaws allow users on Kazaa to share their personal files without their knowledge. In a laboratory user study, only 2 out of 12 subjects were able to correctly determine that Kazaa was sharing their entire hard drive. We looked at the current Kazaa network and discovered that many users are sharing personal information such as email and data for financial programs such as Microsoft Money. To see if other users on Kazaa were aware of this and taking advantage of users ignorance, we ran a Kazaa client for 24 hours with dummy personal files. During this time, files named "Inbox.dbx" and "Credit Cards.xls" were downloaded from our client by several unique users. The tech report is online, or see our lab web page."

    Just out of curiosity, I ran the install myself, and I observed that while the sharing scheme isn't 100% clear or too concerned about the user's privacy, it's still not nearly as bad as the outright installation of spyware, which Kazaa does anyway. I also asked a small group of novice users to try it out, and found that:

    1) The default shared folder is C:\Program Files\Kazaa\My Shared Folder. A vanilla user with a vanilla install would not have had that directory, and would not have any private files in here to begin with. Most novice users I polled understood that this was the folder which the public would access, and that private files should never be placed there. So... simply clicking "Next" on the install repeatedly doesn't endanger the person's privacy. (well, spyware is still installed, but you get my point)

    2) When selecting another folder to share, I found that all of the novice users I polled stored their music in a directory strictly for music, and that subdirectories would contain nothing but music. So, if someone is sharing C:\My Documents\My Music\, they would not be sharing files in the parent directory, where private documents are stored. Realistically, I can't think of too many cases where someone would store private files in a directory made specifically for music. Granted, the user could still accidentally put files there, or accidentally share C:\My Documents, but at that point, it's user error.
    3) When selecting an entire drive to share and download music, eg, C:\, all (yes, all) of the users were unwilling to proceed, as they didn't want files piling up in the root directory, and they didn't like the idea of sharing the entire drive. (though this was never specified in the software)

    So... what I'm saying is: Common sense and "install: next, next, next" seemed to prevail in the small group of novice users I polled... While I agree wholeheartedly that Kazaa does *NOTHING* to discourage or warn users of sharing their entire drives, I guess this shouldn't come as a surprise considering the company's history.

    Oh, there are parallels much earlier in the auto industry.

    For instance - in the teens and twenties - many cars often had a knob or a lever on the dash for setting the spark advance. If the spark is too retarded, the engine has moved on and the exhaust valve is opening, and your opportunity for combustion is passed - the engine will stumble and die. But if the spark is too advanced, the engine will produce too much heat, as the piston is still heading upwards, and compressing when combustion occurs. Of course, as the speed of the engine changes, the requirements for timing the spark changes. The timing at 2000 rpm needs to be advanced compared to 800 rpm. So as you accelerated in these older cars, you had to manually set this lever on the dash to advance the timing so the engine didn't die. This was considered too complex for your average woman of the teens and twenties to handle, so there were various laws passed making it illegal for a woman to drive (I think most states have since repealed these laws. Most states).

    In later cars, ignition timing is handled by a mechanical "distributor" which advances the spark based on the speed the engine is running. This eliminated one whole control, one whole focus of attention.
    Later cars eliminated the high maintenance of the mechanical distributor by replacing it with an electronic timing system (electronic ignition).
    I don't think that there's a single person who will argue that "the old way" was better. Although a lot of people mourn the loss of distributors, everybody's happy about not having to set the timing advance on the dashboard as you accelerate.

    Other improvements include automatic transmissions. To this day, my wife refuses to learn to drive stick. Why should she have to do it when there's a perfectly good mechanical device designed to take care of this needless distraction for you? You can get from point a to point b just fine without a clutch and gearshift lever.

    Of course, macho purists will give you all kinds of rational explanations as to why driving stick is better; you can judge your speed by the engine note and knowldege of which gear you're in, which is obtained tactile-ly, so you don't have to take your eyes off the road to look at the speedometer. Manual transmissions are more efficient. Easier to maintain and repair. Allow more flexibility when you're driving hard.
    None of those things matter to the soccer mom with three screaming kids in the back of the van, trying to get them home in time for lunch.

    These are only a couple of examples of how the auto industry changed to meet the needs of people whose money it wanted.

    If the computer industry wants these people's money - if they truly want to sell a computer for every home - they're going to have to design a computer for EVERY home. Not just the niche geek market. Macintosh made computers more accessible - but not to the poor. Windows made computers more accessible, but simplicity was sacrificed for CHEAPNESS. Linux made computers even more accessible to low income people who were willing and able to "geek out". "modern" Linux (the last 2-3 years) is even more accessible to your typical Windows person - but still has a ways to go to be as simple as a Mac. Personally, while Apple did a great job making Mac OS X a SIMPLE to use Unix, it's a step backwards from the old OS in many ways - as far as mass-market usability is concerned. Nobody really hits that target yet. Or even comes close.
    I think that ultimately, file systems will have to be transparent. Data has to be accessible, without requiring the user to know about a directory structure. I know those sound pretty unrealistic - but I think that's the only way that, in the long run, "normal" people are going to be able to use computers productively enough to justify their use.
