I get irritated by sites with a lot of java, which I guess is inevitable for that sort of thing, although I would have prefered a quick start page that would allow you to opt out if you wanted to avoid java. (That's a general pet peeve of mine,t hough, because this machine gets so bogged down so quickly from java...)

Otherwise, I think it's a pretty cool idea, although I agreet that better categorization would help -- and some sort of coherency checker? At least someone checking to weed out the real trash.
