Bob Murphy thinks I deserved my own entry in Noah Smith's bestiary...
...hmmm. I'm not the one that has a whole post series, set of you tube videos, and charity drive solely dedicated to trolling Paul Krugman, Bob!
It's true, I agree with Krugman often. I also disagree with Krugman (including in the comment sections of one of Bob's more recent Krugman posts where I claim that he makes a bad analogy between the Broken Window and the iPhone, which puts me in the company of that great Krugman-lover Robert Wenzel).
Surely agreeing with Krugman and putting forth arguments to that effect doesn't amount to "trolling", particularly since the only comment sections I regularly participate in these days are Bob's and my own (and occasionally I get in a tussle at Coordination Problem).
No, I don't think that's trolling.
Having a blog dedicated to arguing with Krugman? That's trolling.
Exposing yourself on youtube to try to get Krugman to argue (err... debate) with you? That's trolling (although it is a bit of trolling that I'd personally like to see come to fruition).
It is a very weird state of affairs when (for many people) calling Krugman an economically illiterate partisan hack is "engaging in honest discourse" and me raising the point that he's a decent economist that makes good points is "trolling".
Krugman fans may be a type of troll that plagues other blogospheres... maybe right or left wing political blogospheres. They are not a phenomena in the econ blogosphere. Krugman haters, though...
