The inaugural celeb-Twitter Tournament of Champions has been a rousing, bare-knuckled success to date, concluding this weekend with a battle between finalists Jon Favreau and Rainn Wilson for the title of Best Celebrity Twitterer (in this tournament, anyway). Of course there are no losers here, just a couple guys with a million-and-a-half followers between them fighting for Twitterverse bragging rights. Not to mention their guaranteed invitation to the Celeb-Twitter World Series we're planning to host this fall. Gentlemen, start your engines, and readers, cast your votes.
