Matthew Yglesias bemoans the lack of blogs by specialists. Most bloggers who cover social issues and policy are generalists with opinions, not people with expertise (whether formal or informal) or new information to share. Of course, there are exceptions, and some good ones are listed in the responses to Yglesias’ post. For some reason, most of the exceptions are political theorists and constitutional law professors. There are very few blogs devoted to aspects of public policy (as opposed to electoral politics), other than the few listed on Crooked Timber. I do like these:
There are 3.6 million blogs, and some of them must be highly focused and well-informed. But they aren’t very prominent, and I’d be glad to know of more.
