Another major milestone has been reached by Facebook, the social networking giant. As covered by many global media sites, including the BBC, Facebook has announced that it has now registered its 500 millionth member. In addition, the site has also gained around 100 million new users in the last six months.

As the site continues to expand around the world, largely through word of mouth, the rapid increase in users is expected to reach the next milestones of 750m users, and then 1 billion, in the next few years. Despite recent concerns about privacy on the site, it is clear that many people are not deterred and are either testing the site for themselves or becoming active users.
