Looks like we have more to worry about than just blurting out TMI on your Twitter or Facebook pages: a study reports that nearly half of users polled broadcast when they're out of town on their social networks, leaving them open to potential burglaries.

Seem far-fetched? It's not, as the Arizona man who was robbed in June after tweeting about being out of town can tell you.

It may seem alarmist, but I'm taking this to heart. What makes it tough is that when you tweet all the time, how could you not tell people that you're in a cool city on vacation? Maybe just leave out the tweets where you explicitly say you're out of the house and for how long.
