Imagine walking into a 14-year old girl's bedroom — what would you see on the walls? Probably pictures torn from magazines, drawings, maybe inspirational quotes. Transform that visual collage into a social media site, and you have Pinterest. The site has taken off since its 2011 launch, with nearly 12 million unique visitors in January, 2012, and its membership has been accelerated by Facebook tie-ins that show your friends' Pinterest activity.
So why all the buzz? How does it work? And is it a contender to Facebook?
