Excuse me if this is a bad idea, since I ditched the social network trend after a few minutes on Friendster some years ago. It seems that the design ought to have however many different levels of friends you want, with the inner circles seeing everything on your page that the outer circles can see, plus some more, without necessarily knowing the name of the circle they're in. That way you could have Public (not friended at all) < Acquaintances < Business associates < Family < Close friends (or vice versa, or combining the previous two, depending on how you relate to your family) < Secret circle of shame. Or a directed acyclic graph instead of a single path, I guess, as long as you only allow people access to that feature if they promise they understand how to use it. (Whose social life is that complicated?)
