It used to be easy to manage your privacy settings to prevent things from going public, but in the last few years, Facebook has made it harder and harder to control who sees what information. Some parts of your profile were set to be publicly viewed by default, so if you didn’t know to go in and change it, you were unknowingly broadcasting your party pictures to your boss. At one point I just gave up trying to figure it out, and didn’t know if some of my information was publicly visible or not. I’m not crazy–CNN says the site currently has more than 170 privacy options. No wonder I was lost!
