The entire point of Facebook is to entice people to share every sordid detail about every thing they do in their lives, no matter how pointless or trivial. In fact, the more sordid and pointless, the better--because that's a reflection of a person's "true" priorities and a much better measure of how they actually live their daily lives than any self-censored, banal content they'd put up if they understood the concept of privacy and discretion at all.
