Exemplary intellectual discourse

I've gotta hand it to Greg Mankiw - while he is wrong on cap-and-trade, there is so much to be commended in his modus operandi. He links to pieces disagreeing with his premise; he links to pieces disagreeing with his conclusions; he posts wonky follow-ups to explain his thoughts in more precise technical terms; and his air throughout is inquisitive, unegoistic (is that a word?), respectful, and without a whiff of personal attack. There is much to learn from him (not to mention Jon Stewart)...
