For some reason there's been a spate of nastiness lately. I don't know why - maybe it just got kicked up by Ferguson. One thing I do know is that if it escalated I'd feel obligated to read up and comment. Krugman's relative patience in the face all the haters is otherworldly. Very impressive. And when he's not patient, the times when he is makes it more forgivable.
I'm with Noah Smith, though. I'm personally more of a DeLong yes-man than a Krugman yes-man. Krugman is more likely to overstate his case or comment prematurely. Makes it harder to be a good yes-man. I guess I'm technically still in the "claque" though (I did not know this was a word before reading Ferguson [well, the beginning of Ferguson... I couldn't stomach reading too far], so that's at least something he offers).
