I quit facebook 4 days ago and convinced my friends to leave too. It wasn't easy because I had way too many associations through facebook, but luckily my facebook email was the same as my accounts sign-up email, so it wasn't much of a hassle. For some of my friends who don't manage their emails and accounts on the internet well, it was a living nightmare. The only thing I miss about facebook is gamer room, it really pinches me to loose all my facebook games progress.
