Can I ask you now a little bit about the product Facebook. You tell us that in essence the company develops technologies that facilitate the sharing by individuals of their information through what you call the social graph, the digital mapping of people's real-world social connections. Anyone over the age of 13 can sign up, but you wish to emphasise that Facebook does not itself produce the content that is shared via the service.
You tell us a little bit more detail about the platform. It's made up of core site features and applications. Fundamental features include a person's home page and timeline. There is also a news feed -- it's not news in the sense that we may have been using it, but this is news about a user's friends and what they are posting?
