This concept came out of StartupWeekend Columbus 2010. The core idea is that we're all following way too many people, and that odds are we have serious chumps lurking in our friends list. Everyday you play lottery on your friends, the game randomly picks a winner from your friend list- tells you a bit about them (# of replies, DM's, klout score etc) and then you decide, save or dump them. Players can override the lottery and dump on demand if they play more.
