Now I like this site, but what really annoys me is the amount of spammy mail I get off them. "Sam likes your picture. Ben commented on your status. SO WHAT? i find that out when I log in for heavens sake!
some applications spam way too much. and also many applications are trying to make you buy stuff for the game (can be bad for children...) also when it comes to privacy fb is not good enough. don't know how many times I have made a photoalbum between me and some friends, and people who's not supposed to see them still can!
and not a good place for a child to create a profile without the parents being a friend with the children!
