Why you mean by "quit your friends"? About 50% of my friends are not on the Facebook, and I communicate with them using phone, email, or directly meet them. The same with the folks who are on FB...I usually reach them by other means, anyway.

Really? For me it's down to <10% Friends. (Maybe 50% of family when you count aunties/uncles) And aside from 3 people I don't remember the last time I got an email from a friend. FB Messaging / wall posts own that space completely.

Obviously sms still has it's place (ie- want a response in the next 10 minutes rather than the next 24 hours) and nothing can replace in-person communication -- but FB is doing a damn good job of replacing my electronic communication.
