Who's your doppelganger?  

It's doppelganger week on Facebook, and it's spreading like wildfire.  Some are even saying that it is more successful than the bra color statuses that occured a few weeks ago.  Status updates are as follows:

"It's Doppelgänger week on Facebook; change your profile picture to someone famous (actor, musician, athlete, etc.) you have been told you look like. After you update your profile with your twin or switched at birth photo then cut/paste this to your status."

If you are lucky enough to look like Angelina, or you have been mistaken for a celebrity, change your profile picture!  There is an application, FaceDouble, that will match a celebrity to a picture you upload to the system. This is just another example of how social media can spread like wildfire, even if it isn't for a social cause.  Read the article here, and make sure you update your profile picture!
