What a bloody waste of time this is. It's a blatent popularity contest. I mean, does anyone really believe that Mozdev is the third most usable site on the web?

Two other things: comments aren't working (might sort it out tonight) and ASP.net is fucking retarded. By default is produces invalid html. I'm going to try overriding the server controls to get them working sensibly, but what the hell was MS thinking of?
