Roll over Facebook, here comes Pinterest

Facebook and its IPO might grab the headlines but image-sharing site Pinterest is grabbing viewers.

“According to comScore, Pinterest usage in the U.S. shot up from less than half a million unique visitors in May 2011 to nearly 12 million in January 2012,” eMarketer reported today. That’s a faster rate of adoption than the latest darling of the social media world, Tumblr. U.S. traffic at that blogging site traffic rose from less than 7 million unique visitors in late 2010 to more than twice as many a year later, comScore reported.

According to its website, “Pinterest is a virtual pinboard. Pinterest allows you to organize and share all the beautiful things you find on the web. You can browse pinboards created by other people to discover new things and get inspiration from people who share your interests.”

You just can’t get stock options at this point.
