Facebook is six years old. What started as a semi-private communications channel for people at Harvard University has grown into a global network that claims 500 million active users. That would make it the third-largest ‘country’ on the planet and the company’s estimated market value is around $22 billion (unlike Google, Facebook is not listed yet).

Facebook has received a lot of attention in the media for its privacy policies, with plenty of negative commentary from privacy advocates, high-profile users and even some focus from governments in various parts of the world. For users and the businesses they work for, this is a concern.
