4.8 million broadcast when they’re leaving the house, 4.7 million about health conditions, 4.6 million about their love lives and 2.6 million about alcohol use, according to that study.

How can sharing this kind of information become problematic? If the wrong person knows when you’re leaving home and for approximately how long, that hypothetically makes a burglar’s job much easier. Sensitive details about relationships and wild stories (or photos) of drinking and partying can leave the door open for blackmail or extortion. And personal information such as a full birth date or health condition can make users easier targets for predatory scams.

Of course, many of these potential pitfalls can be avoided by remembering the cardinal rule of social media — privacy settings are key.
