Hitwise recently reported that MySpace.com received 74% of U.S Social Networking visits for April 2008, down from 78% in April 2007. Facebook on the other hand saw its market share rise from 11% in April 2007 to almost 15% in 2008 (a 32% gain).
Without looking, can you name the top five social networking sites in the U.S. by market share? Myyearbook.com really surprised me as it does not get much mainstream media attention, but it has quietly taking the third spot in the U.S. from Bebo.
