Having dealt with the product in outline, and the corporate structure, can I ask you, as I did with the witnesses from Google, a little bit about Facebook's approach to privacy in principle, please. Can we start with the document at tab 11 of the bundle. It's an article published by the Guardian on 11 January 2010, so just over two years ago, reporting the words of the Facebook founder, Mark Zuckerberg, and he was saying that he thought that privacy was no longer a social norm. He's quoted as saying -- I'm looking at the third paragraph:
"People have really gotten comfortable not only sharing more information and different kinds, but more openly and with more people. That social norm is just something that has evolved over time."
Can I ask you: what it is Facebook's approach in principle to the privacy of information?
