Facebook becomes most popular U.S. Web site

I just saw from SmartBrief that “Facebook overtook Google as the U.S.’s most popular Web site last week, according to a report by Hitwise. Checking Facebook accounted for more than 7% of all Web visits, the report found. A recent swath of surveys further underscores the platform’s importance for social marketers. Studies show that the average American spends 7 hours a month on the site and that 44% of all social sharing takes place on the platform.”

This is totally amazing!
