It is so wierd. I have had facebook for the past 8 years, largely as a way to peer into lives of people I envied, as opposed to keeping in touch with old friends.
I really struggled in the transition between high school and college and I feel facebook has held me back significantly. I have accomplished a great deal since the summer of 2008, but I feel facebook has been this ball and chain that has been dragging me down,slowing me down the whole way.
One week without it.. it feels like I am slowly awakening. I have far more free time, care about my own life, and more importantly know who my true friends really are.
The more I think of it, the more stupid/dangerous facebook is. Yes you get to keep in touch with old friends, but you are volunteering your information to total strangers. Creepy "friends" of yours can check out your profile.
Hitler,Stalin, Saddam and others would have loved it if facebook existed when they were in power (Saddam missed it by a year.) That way they could monitor their own people, and their people would voluntarily give up info about themselves!
