I agree about Facebook. I don't have an account and never will. ...
Funny
Even *this* Olde Phart is on FB, so is Omar the Impaler (T Cro). It DOES take some getting used to, and you need to be aware of your own personal security settings on FB.
Right now my 'post' profile is "world" (so anybody can read my lame posts), but only Friends of my Friends can ask me to "Friend" them. And if it gets intense, I can shut that down and revert to hermit mode where nobody can ask me to be a 'Friend'.
I used to get a few "Your buddy Hal just earned 50 points playing Angry Birds in a Tar Pit", but you can flag them so you don't see them ever again. And you can unfriend people, as well as just hide their posts.
It is a cool tool. Never say never... I had the same opinion as you. Just be aware.
