Just to be clear, real identity has been at the core of what Facebook's done since the beginning, and we firmly believe that that's why, for the typical user of Facebook, they can be using it day in, day out, month in, month out, and never come across objectionable content. It really is a rare experience that one comes across content that is problematic on the Facebook platform, and that's because most people are feeling accountable. When they do something on Facebook, it's literally in front of their friends and family, and therefore -- people will overstep the mark, but they're much less likely to do so.
What we've also found with our partners, that's been one of the reasons that Facebook has been taken up to such a high degree, so, for example, many newspapers now will use Facebook identities for people wanting to comment on the site. So you read an article, and instead of commenting as "Angry of Tunbridge Wells", you now comment as Richard Allan, and they found that people commenting in their real identities will engage in a better discussion than they would do when they were Angry of Tunbridge Wells.
