> I've never been worried about my employer seeing my social media profiles. If I wouldn't do something in public, I wouldn't post it to social media. Maybe I'm unique in being able to restrain myself.

Me either, but maybe there's a chilling effect going on here.

EDIT:

I personally believe this is because it's orders of magnitude easier to be negative than positive. Negativity breeds more negativity and drama. So, when people quit Facebook they get a boost from not being around so much negativity.
