You don't have to agree with everything he writes to appreciate the work of Thomas L. Friedman. He just makes sense. When he lashes out at the U.S. addiction to oil, or calls out politicians on energy or Iraq, or flattens out the world as we know it, he's generally got the insights and experiences to back it up. Over the years, he's won Pulitzers and a gaggle of loyal readers. And the new edition of his book, The World is Flat, is out in paperback. We'll talk to him about the current state of flatness, about Iraq, China, and oil. If you have questions for Friedman, post 'em here.
