Here's a site that illustrates social media's downside and potentially evil purpose.

Please Rob Me links to your posts, updates and tweet then lists all the empty homes out there for would-be burglars, stalkers and evil-doers to invade.

With more and more people jumping on Twitter, Foursquare, Gowalla, etc and telling others every little bit of minutia about their lives, the potential exists that they can easily be taken advantage of.

Hey, you feel compelled to let the world know you left home and are now at Pizza Village or are "checking in" during a weeks vacation in Aspen, then you could be open for harm.

(That's as much a note-to-self as is it a word of warning.)

Although this site is meant to raise awareness and claims not to promote burglary, the fact remains that the downside of social media is that this could happen.
