by the end of this year people will realise that there is life outside fb.
Facebook is stupid because it has become a social obligation to "friend" people on it, and like you pointed out, way too hard to set up effective privacy measures.
Normal people are scared of public speaking.
My english professor this semester has this crusade against facebook. There have been very few classes go by where he doesn't connect what we're reading about with how facebook is causing the decline of civilization.
