I am pretty terrified of anything to do with facebook because I don't want anyone from my town I grew up in knowing about my transition. Better just to leave those people behind, but it sorta sucks because sometimes facebook could be useful for things. I could make a new account and not tell it my high school or college I suppose, so it doesn't suggest people, and also refrain from adding people that it might connect me to - seems like more hassle than it's worth though.
Maybe the privacy controls have evolved since I last had an active account though, and I am being paranoid for no reason. But, I'm also 3k miles away from my home state and it is really nice being isolated from all of it.
