#FridayFunFact3: Pinterest is now the third most popular social network in the U.S. behind Facebook and Twitter. The image bookmarking site has grown exponentially since the site launched in March 2010. There were 21.5 million total visits to the site during the week ending January 28, 2012, which is nearly 30 times the number of total visits that Pinterest had received six months earlier. From January 2012 to February 2012, traffic went up 50 percent.
Another Pinterest fun fact!
