OT but Anyone actively pumping out stuff for node.js? I just installed it on my slice last week; it took me about an 30-40 minutes to get through the README :| (mostly due to some missing dependencies), flipped through man, and was like wtf I'm doing. . .point being, it seemed like it'd take some serious investment to, first, figure what you're doing, and, second, to produce something interesting.
Coolest application I've seen come out of node.js is http://mrdoob.com/125/Multiuser_Sketchpad_HTML5. I'd be interested in what others are doing in it; let alone, how they got about doing they wanted to do in it.
