I wanted to point out the update at the end of the "Cold Equations" post below, in case anyone's interested. There's been a lot of mail on this one, as you'd imagine - but so far, nothing defending Gregg Easterbrook's analysis. If anyone out there is minded to do that, I'd like to hear it. Nor have I heard from the man himself, and his original post remains in the same inaccurate state in which it was born. Is it a blog if you never update a post or revisit a topic?
