Facebook and security economics

Studies about security economics are always interesting, and Ross Anderson is probably the biggest name on that. He just wrote a small but very nice piece for the New York Times about Facebook. You can read it here. I love this part:"Finally, Facebook might lock in its users even more tightly than Microsoft. People want to use the sites their friends use. As one of my students put it, "All the party invitations in Cambridge come through Facebook. If you don't use Facebook you don't get to any parties, so you'll never meet any girls, you won't have any kids and your genes will die out."
