For any twitter folks out there, here are a few links that are pretty cool.
(2) Bob Lee (better known as Crazy Bob) from Google created Twubble, an app that can help you find more folks you may know on Twitter based on your friends. I am pretty sure it maps off of Google's Social Graph, which is pretty neat.
What I'd like to see? An app that utilizes the Open APIs that Facebook and Twitter have so that I can figure out which of my 500 FB friends use Twitter. Anyone interested in building this for Web 2.0 Expo? If so, I'll buy you a beer next week. If you use Social Graph to build it too, that would be pretty neat... is it possible? /LC
