Facebook is not as bad as everyone says. You can only accept friend requests from people you know, and you can delete anyone you don't like. Whatever content you have on your Facebook is pretty much whatever you want it to be. Plus, people are usually afraid to say too much since it's anchored to their real identities.
Typically people get far worse when they are protected by anonymity versus something like Facebook, at least in my experience. I don't know what Twitter is for, other than live news in disasters from people affected.
It's funny. The Internet sort of grew with a bunch of small, specialized anonymous forums like this one, but these days most of them seem kind of gone in lieu of places like FB, or they are semi-forums that are so massive there is not much continuity to them like Reddit. Although, funnily enough, the most chaotic and loosely structured forum ever made has managed to stick around: 4Chan. But 4Chan has always been too chaotic to be super meaningful, other than as Internet pranksters occasionally.
