Mostly a nitpick, but it'd be nice if the home page had a little <noscript> text for those of us who browse safely and are wondering what it is at a glance or why we should care enough (besides the Spolsky reference) to enable scripting.

Anyway, it's pretty slick with the UI. I'm going to check it out for tasking myself, and if I like it see how it works for a school project with others.
