I thought I would take the occasion of this blog's 400th post to say a big THANK YOU!! to the people who have helped to make it successful. The regular commenters are a very important part of this blog and I'd be lost without you since there is no way I would have been able to personally answer all of the questions that have come in. And thanks to the folks who have submitted some really interesting and though-provoking questions!
I didn't think we'd get to 400 posts in less than three years, so it will be interesting to see how quickly we get to 500. :)
