I interviewed Freakonomics' Stephen Dubner about his favorite shoes, anchovy paste, and why he likes Microsoft Word

On my Cool Tools podcast, which I co-host with Kevin Kelly, we interviewed Stephen Dubner. Stephen's an award-winning author, journalist, and TV and radio personality. He's co-author of the Freakonomics books, which have sold millions of copies in 40 languages, and he's host of Freakonomics Radio, which gets 8 million global monthly downloads and is heard by millions more on N.P.R. stations and other radio outlets around the world. Here are the show notes.
