With Twtroulette, users can now visit what industry notables like Mike Arrington, investor Brad Feld, and YouTube's Hunter Walk see when they open Twitter i.e. what it's like to follow the people they are following. People can also volunteer their own timelines by adding themselves to the directory. And, like Chatroulette, there's a random function so one can shuffle through profiles if they're feeling lucky.
