So this nonsense about you've got to have real names on Facebook and whatever, that gets you that kind of security. That gets you security theater, where there's no actual security, but people are sort of playing parts in a play about security. And as long as everybody learns their lines, everyone's happy. But it's not real security. Especially because I hate banks more than the G20 protesters do, because I work for them. I know that things are actually worse than these guys think. (Laughter) But suppose I worked next to somebody in a bank who was doing something. Suppose I was sitting next to a rogue trader, and I want to report it to the boss of the bank. So I log on to do a little bit of whistleblowing. I send a message, this guy's a rogue trader. That message is meaningless if you don't know that I'm a trader at the bank. If that message just comes from anybody, it has zero information value. There's no point in sending that message. But if I have to prove who I am, I'll never send that message. It's just like the nurse in the hospital reporting the drunk surgeon. That message will only happen if I'm anonymous. So the system has to have ways of providing anonymity there, otherwise we don't get where we want to get to.
