From New York Times:
Facebook, which surpassed MySpace in 2008 as the largest social-networking site, now has nearly 500 million members, or 22 percent of all Internet users, who spend more than 500 billion minutes a month on the site. Facebook users share more than 25 billion pieces of content each month (including news stories, blog posts and photos), and the average user creates 70 pieces of content a month. There are more than 100 million registered Twitter users, and the Library of Congress recently announced that it will be acquiring — and permanently storing — the entire archive of public Twitter posts since 2006.
