> Do people who use facebook actually care about privacy?
Many people probably both use Facebook and care about privacy. Many probably would rather quit Facebook but think they can't because a part of their social life they think important is there. Or even a part of their education is (many students have a Facebook group for their class).
I sympathize with you but it would help to try and understand people who care about privacy but still use Facebook if the goal is to solve this problem.
I've had luck so far I haven't got trapped in Facebook though.
