From Ther Article: "Pinterest is the third most popular social website (Experian traffic report April 2012), just behind Twitter and Facebook. In just over six months, Pinterest has become more popular than LinkedIn, Foursquare, Instagram, and Google+ (based on traffic volume).
You don’t have to be a lifestyle-type site to win on Pinterest, you merely need to make your brand fun and create interesting, shareable images.
Pinterest offers other benefits, including social links generated from content shared on Pinterest".
