facebook as a weapon

There are many good things about having Facebook -- hooking up with people you haven't seen in forty years, for instance -- and there are just as many bad things.  You've read about the cyber-bullying and all that extreme abuse.  But there is also the personal contact that Facebook replaces, the way people can use it to hurt each other, and the way bad news is often transmitted these days.  People find reasons to "de-friend" each other or leave Facebook, offending in ways that didn't use to be possible.  I sometimes wonder if Facebook has peaked.  As soon as somebody gets pissed enough, they drop out, and, the way things are going, we will get all get pissed enough eventually.
