Heading Out? Tweet the Burglars

A new website is out to make people think twice when they use Twitter, Foursquare, or any other social networking tool to let others know when they're not home. The site's name says it all: PleaseRobMe.com. It aggregates publicly shared check-ins and caters jokingly to hypothetical burglars looking for "new opportunities," notes Mashable.

"The danger is publicly telling people where you are," say the site's creators. "On one end, we're leaving lights on when we're going on a holiday, and on the other we're telling everybody on the Internet we're not home."
