LB, the 'follower' business made me feel slightly stalked, but I rather like the Jesus thing 
I agree on the 'friends' thing, which is why there aren't many people on my facebook, and those that are tend to be my real friends. All that happens if you add people you don't know or never really spoke to is you either ignore each other completely (like you would in any other scenario) or you maintain a really superficial level of contact (i.e. send the occasional My Little Pony to show you 'care').
