A friend and I had a conversation related to this last night. We were speaking about how Facebook has seemed to become the dumping ground for acquaintances that you'd like to keep in contact with, but never will, and who you're not really comfortable texting. It's a problem I've had with Facebook for a while. They just don't differentiate the relationships I have with people enough. And because almost everyone is on the same level, I'm hesitant to share information and act as I would if it were just me and my close ring of friends. Often times, others will just post things to garner attention because they're posting to the world, and so my news feed is usually cluttered with garbage I'm not really interested in.

Anyway, I think adding points to relationships, or even people really, is a good way to go about differentiating friends. Come to think of it, I can see a Facebook app where you have 3 tokens to choose your top 3 friends to be pretty successful. Throw in an option to let people buy more tokens to add more best friends, and you'll have a bunch of teenagers buying tokens so as to not make the 4th and 5th best friends feel left out. :P
