I don't find it a challenge to use. Often I have to tell my parents how to use it and they still don't get it.
As for stuff like privacy and social skills, well, I don't put anything on there that I wouldn't feel safe with just anybody knowing, and I don't try to make any new friends; just use it to keep contact with friends I already have.
