What features of Facebook do you hate?

It is undeniable that FACEBOOK (as in caps) has truly changed the way people around the globe live. and there comes a point that I suddenly get frustrated/annoyed to this networking site. I don't know but I get this feeling of smelling a foul dead wall (peed and pooed by the public). that feeling of being into a very PUBLIC place (as in). well, I just hate it when people broadcast even most little and corny and senseless things that happen to them. It freaking ANNOYs me a lot. and when I see the random facebook wall, posted even the private activities of some (e.g. writing on others' wall). Well, so much of it. I just want to know if there are others that feels the same way like mine. thanks!
