If anyone thinks this validates putting up pictures of yourself doing stupid stuff and listing your favorite sexual positions because 'hey a bank in texas' is nervous that something you PUBLISHED to the Internet is an invasion of privacy, then you are probably also one of those people who thinks because one time someone stopped on the NJ turnpike to avoid hitting a kitty, that you can walk across it at will.
Anything you are actually publishing to a publicly visible page cannot EVER be misconstrued as your private business. Any lawyer who was actually awake can pretty easily convince a jury that you were actively promoting whatever behavior it was that they are looking at. The idea that a social site gets a special privelege over any other website is like saying 'hey I was on a reality show... People are supposed to act stupid on those!'
Your employer is likely to do a credit check for goodness sake. They can make you pee into a cup. Do you really think any large company is going to risk hiring someone into a position of responsibility when they are actively promoting themselves as a drunkard, sex-addict, racist, or any other of a thousand image crushing stereotypes?
If anyone actually breathed a sigh of relief, they should suck that air back down. We are not moving towards an error were there is more privacy. This is not a bellwether. The only thing that might happen is that you will be required to sign a form saying you waive your right to privacy if you are applying for a job. And you will.
