Last year was certainly the year that Facebook spread its wings, and 2011 is already shaping up to be even bigger and better for this social media giant. By the end of 2010, Facebook had already surpassed Google to be the most-visited website in the United States. A recent study from Experian Hitwise disclosed that Facebook earned 8.93% of all website traffic last year, while Google shrunk to a still modest 7.19%. The previous year in 2009 held Google at the top of the list followed by Yahoo mail in second and Facebook in third. With such amazing growth rates unseen be even its largest competitors it looks like Facebook is going to remain unchallenged as top dog for years to come.
