So the second example I thought I'd use is chatrooms. [Chatrooms and Children] I'm very proud of that picture, that's my son playing in his band with his friends for the first-ever gig, I believe you call it, where he got paid. (Laughter) And I love that picture. I like the picture of him getting into medical school a lot better, (Laughter) I like that picture for the moment. Why do I use that picture? Because that was very interesting, watching that experience as an old person. So him and his friends, they get together, they booked a room, like a church hall, and they got all their friends who had bands, and they got them together, and they do it all on Facebook, and then they sell tickets, and the first band on the - I was going to say "menu," that's probably the wrong word for it, isn't it? The first band on the list of bands that appears at some public music performance of some kind gets the sales from the first 20 tickets, then the next band gets the next 20, and so on. They were at the bottom of the menu, they were like fifth, I thought they had no chance. He actually got 20 quid. Fantastic, right? But my point is, that all worked perfectly, except on the web. So they're sitting on Facebook, and they're sending these messages and arranging things and they don't know who anybody is, right? That's the big problem we're trying to solve. If only they were using the real names, Then you wouldn't be worried about them on the Internet. And so when he says to me, "Oh, I want to go to a chatroom to talk about guitars" or something, I'm like, "oh, well, I don't want you to go into a chatroom to talk about guitars, because they might not all be your friends, and some of the people that are in the chatroom might be perverts and teachers and vicars." (Laughter) I mean, they generally are, when you look in the paper, right? So I want to know who all the people in the chatroom are. So okay, you can go in the chatroom, but only if everybody in the chatroom is using their real names, and they submit full copies of their police report. But of course, if anybody in the chatroom asked for his real name, I'd say no. You can't give them your real name. Because what happens if they turn out to be perverts, and teachers and whatever.
