Officiating the Krugman v. Chicago Fight

My throwaway line that some people at the University of Chicago "reeeeaaaally didn't like Paul Krugman's article about the state of macroeconomics" has gotten so much traffic, thanks to a link from Krugman, that I feel obliged to go a bit deeper. My observation was occasioned by a conversation with a couple of mild-mannered, open-minded finance professors who aren't directly involved in the debates at the heart 0f Krugman's article. They mainly just thought Krugman was being rude and unscholarly.
