Facebook already has groups. So make your friends group, your family group, your coworkers group, and your BDSM group, and when you post anything, make sure you mark which group(s) to post it to. Facebook actually makes it pretty easy to do so. The author mentions groups but basically claims laziness as an excuse.

And of course, if you don't want anyone knowing what you're thinking or doing, DON'T POST IT.
