I'm coming to the opinion that the core problem Krugman is having is that he has a column, which is nice in that it allows him to express opinions and attempt to influence policy.

At least in a blog or a forum, there are comments which people can examine to see counter-arguments and perspectives immediately valuable to the topic at hand. NYT columns, not so much.
