Why Facebook? Facebook - as you probably know - is the world's largest social network. According to the company's statistics, the site claims more than 400 million active users - more than the entire population of the U.S.
More importantly, people visit Facebook regularly. Over 50 percent of all users log into Facebook every day. According to Compete data from December, 2009, thirteen percent of all Web traffic to major portals AOL, MSN and Yahoo! comes from Facebook - more than even Google.
Users have come to rely on Facebook to stay connected to the Web. Clearly, if you have a Web presence, it should be connected in some way to Facebook.
