MarkBaynard: If you start hanging out over here, won't your Facebook Friends miss you? Abby_Donovan: Those people weren't my friends. If they had been, they wouldn't have sent me all those annoying quizzes. MarkBaynard: A true friend never asks you to feed their imaginary fish. Or fertilize their imaginary crops. Abby_Donovan: Although with a little coaxing, I might be persuaded to take home your imaginary kitten. So how is Twitter different from Facebook? MarkBaynard: Twitter is the perpetual cocktail party where everyone is talking at once but nobody is saying anything.
