I don't have a facebook either nor will I ever have one. I have a myspace and its ridiculous enough, the facebook is just one "look at me, look at me" site for 'networking' on.
You have no clue how so very very wrong you are.
It is NOT a MySpace, and the privacy options you set on your account per user is phenomenal.
Don't judge it - until you've used it.
You'd be very shocked to find out how thrilled you are to use it over MySpace - or anything for that matter.
