Pinterest has practically caught up with Twitter, with 15 percent and 16 percent of adult U.S. Internet users on each network, respectively. Pinterest, which launched in 2009, has experienced explosive growth, especially with a white, female and affluent user base. Women are five times more likely to use Pinterest (5 percent vs. 25 percent) and almost twice as likely to be white and college-educated. It’s become a magnet for hip urbanites searching for the hottest wedding gowns and apartment decor. Twitter, however, gets a lot more attention, since neither presidential campaigns nor Middle Eastern activists are leveraging style catalogs to rearrange their countries’ political leadership.

Amazing that Pinterest keeps growing.

And amazing that Twitter is used by far fewer people than I think.
