Initially launched as a social networking site for American university students, Facebook now has 500 million users worldwide. People are using the site to meet new people, keep in touch with friends and family, spy on people who don't know how to make use of the privacy settings, play games and much more.
If you've ever wondered what a map made up of Facebook users would look like, then you'll enjoy the graphic below.
