Saw this from the beginning and never signed up for a Facebook account. People look at me in a weird way when I tell them I don't have one, but they definitely go "hmmmmm" when I tell them why. I believe the term is sheeple. I prefer not to give some entity something of myself without real compensation. Do you really want anyone knowing everything about you?
I believe there is a real market for a private Facebook. Most people pay more than $80 bucks for their phone. Why not a couple bucks a month for something like Facebook that will not sell you out to the highest bidder? Until that happens, email on a private server that you control (i.e. not gmail) is the way to go.
