Of the 23,160 Facebook applications, I use about 5, but I probably wouldn't notice if someone randomly removed all of them from my profile in the middle of the night. Kids these days. I used to play BlockStar, but haven't used it since it changed to Tetris (formerly BlockStar) and haven't played Scrabulous since my 1,000,000th consecutive loss. What Facebook applications do you use (or not use)?
Speaking of Facebook, have you joined the FlowingData group yet?
