Trolls of the Econo-blogosphere

Trolls are usually those who disrupt a particular blog or message board, intentionally or unintentionally. Greg Mankiw is an econo-blogosphere troll. He disrupts the workings of the econo-blogosphere as a whole with his insipid posts. Eventually, Brad DeLong gets tired of the stupid, and fires off a nasty blog post. But it's really kind of a waste of time. Mankiw has sacrificed any semblance of credibility at this point, and should be ignored. I understand how those who respond to Mankiw, McArdle, and others of that ilk feel. Their intellectual dishonesty is infuriating. But acknowledging them is just feeding the fire. At some point, the only thing you can do is ignore them.
