The Failstate Whale: Tweet Trumps
I forget who mentioned this at GameCamp, but I've finally tried it out. It's Tweet Trumps! As in, it's Top Trumps... but with twitter. Basically, it looks at any given username and works out who is mutually following who, and then presents the statistics about those accounts in the Top Trump format. I'm pleased with my ability to work out which of my friends are actually sweariest. Go try.
