According to Hitwise, Facebook passed Google becoming the #1 site in the U.S. measured by number of visits.  The number of visits to Facebook also continues to grow at a strong clip, up 185% from March 2009 to March 2010.

Facebook's platform business is one of their drivers of traffic growth.  The social game Farmville, for example, is built on Facebook and has experienced amazing user growth. 

With Facebook offering application developers easy access to hundreds of millions of potential customers, we expect the number of Facebook apps to growth dramatically over the next few years.  We also believe the types of 3rd party applications available on Facebook will move beyond games and entertainment to a wide range of application spaces.

Facebook as an application platform is a key reason we think Facebook may be taking over the web.
