Cool, cool. Cool, cool, cool. So now who gets to build a facebook-based credit score optimization app. Buy and sell your friends so you can buy a house/get a job.
this could have the potential to break the concept of facebook (though it has managed to do much of the damage on its own) in that it makes you unfriend people so you don't have a negative mark, and add friends you don't like or socialize with, and force you to talk to them, just to help your chances at a loan... seems like the only facebooks true purpose will be lost
Nah, you just need a second FB account just for these purposes.
Or a friend suggestion app to increase your score
I would assume that any friend that helps your score would have their score hurt by being your friend.
Eventually everybody simply shares the same credit score.
Not necessarily. Say you both have the same credit score. If you befriend eachother, that reduces the negative impact of friends with lower scores for both of you, by reducing their overall weight.
