You'd never put a sign on your front lawn saying you'd left town for the weekend. And it's very unlikely you'd give your address to a stranger as you wait to board a plane for vacation. Yet according to an AOL Travel story, people using social networks such as Facebook leave themselves vulnerable to having their homes robbed by posting something as innocent as "Leaving the cold and snow for a week in Florida."

Since so many of us use our real names -- or even post home phone numbers on information pages -- it's all too simple for people with bad intentions to break into an empty house and help themselves to its contents. Plus, statistics show that 13 percent of unsolicited "friend" request are accepted -- even from total strangers. Maybe a little old-fashioned caution is the way to go.
