Facebook's total lack of respect for your privacy wasn't enough to get you to quit.  All the studies about how Facebook leads to depression weren't enough either.  Will this finally be enough?

Apparently, now your Facebook friends can affect your credit.

There are a handful of new companies that are analyzing your Facebook friends to determine whether or not you're a safe bet for credit.  If you have friends who are delinquent on loans or default on loans, it reflects badly on you.

For now, it doesn't look like there's any connection between your Facebook friends and your FICO score.  So being friends with a bunch of bad credit risks won't drop you from, say, a 750 down to a 610.

But there's no reason to think a company would only consider your FICO score for a loan in the future.  If they can get a better picture of you by looking at a second credit score, based on your Facebook friends, why wouldn't they?
