Steven D. Levitt and Stephen J. Dubner, the Freakonomics guys, recently spoke at the Google campus and blogged about it. The best Googler question of the day: “What would you do with our data if we could give it to you?” No answer yet but they say they’ve been thinking about it quite a bit ever since.

Also, there’s now a regular Freakonomics column in The New York Times Magazine. “Up in Smoke” is the latest piece. It tries to explain why the media doesn’t pay attention to crack anymore (short answer: Crack-associated violence has largely disappeared).
