When I started my economics blog ranking, I caught some flack for choosing to exclude the excellent and popular Crooked Timber blog. It’s written by16 academics and intellectuals and does have some posts about economics, but many more posts about politics, academia, and other miscellaneous topics. So I decided that while it was a high-quality blog, its main focus wasn’t economics, and chose not to include it in my list.

Now I face a similar dilemma with Paul Krugman’s blog. Krugman is a very famous and gifted economist. He’s written many important and respected academic papers in economics and is a professor of economics at Princeton. But I’m having some doubts about whether his blog is really about economics. Looking over his recent posts, there are a few about economic issues, but many more about American politics and other American domestic issues, perhaps with a little bit of economics thrown in, such as the relationship between income and voting. So, is Krugman’s blog an economics blog or not?
