We Need Your Questions

There is going to be a U.S. paperback edition of Freakonomics someday, and when there is, the publisher wishes to include a Q&A with the authors.
Such Q&A’s have great potential but often fail because of the canned and bland questions fed to the authors by the publishers — or, worse, fawning questions invented by the authors themselves.
So let’s put an end to that!
In the comments below, please pose some questions that you would like to see answered in the paperback Q&A. They can concern anything you’d like: material in the book, modes of collaboration, the price of tea in China, material in the upcoming SuperFreakonomics, etc. We will probably use 8 or 10 or 15, but the more we have to choose from, the better off we’ll be.
Thanks!
