I quit fb in 2013. It's a pesky habit to kick. I was an early adopter, early 2005. In fact, as soon as I got my .edu email I signed up. I tried giving it up several times. I could go without saying how much easier it is to leave fb when someone else does it with you; Finally, my future wife and I gave it up together at the same time. Present day, the unfortunate thing is certain apps only use fb auth and if you want all access to work with fb for developers, your only option is to login through a fb acct. I imagine if you wanted to work for fb one might need a fb account too.
