By the end of March 2012, Facebook claimed more than 900 million monthly active users, more than half of whom did some sort of daily Facebook activity, such as clicking the Like button. In other words, nearly one in seven humans use the service semi-regularly. Facebook is a global phenomenon: 80% of its users live outside of the U.S. and Canada, and the service is available in more than 70 languages. Daily musings are popular, of course, but so are photos. In the first quarter of 2012, Facebook fans uploaded more than 300 million pictures per day.
