Not that it really matters at this point, but I didn't come here from Andrew's site to comment on this link specifically, but I had watched it earlier in the day and came across it here completely randomly.
Most of the people Andrew interviews will play ball--he pushes back on a short answer, asking for more, and they oblige (thinking specifically of Noah Everett... he wouldn't stop opening up!). Not so with Godin, he tells you what he wants you to know and no more in an attempt to lead you to find or stumble on the insights that will help you learn more about yourself and what you do well.
