I've been picking on Mankiw lately. Nothing should be read into that. He's undoubtedly at least 56% smarter than me, and he is one of the greatest economists of our time in my opinion. I consider myself a New Keynesian so I rever him in many ways. Besides, he's got the best econ blog on the web - so I have to post about him all the time - even though we often disagree. Besides, I love his text book(s).
It's amazing how much I have changed over the last 3 or 4 years. I don't think Mankiw is one of the 'greatest economists of our time.' I definitely don't consider myself New Keynesian anymore (I blame my schooling for indoctrinating that into me). And I certainly don't think Mankiw has one of best blogs on the web either - especially since he stopped allowing comments. And, above all, his textbooks are the most generic, least explanitive, most indoctrinating books on the market - yuck, yuck, yuck. Not to be overly critical, but I mean really... I know his texts are popular, but they are just not very good - pretty and popular, but not good.
