I think I've decided that Matt Yglesias is headed out of my RSS feed. It's not that I find him ideologically objectional or his work to be shoddy but rather that he has become utterly banal. He is a generalist to a fault, applying his well developed sense of logic and reason to an enormously broad set of topics. Increasingly I am finding that his analysis, while logically coherent, suffers from his lack of even a minute amount of substantive knowledge of the topic at hand. For example, he has essentially zero practical real world experience with state or local government and so his postings on topics like education, taxation, transportation, planning or just plain governing come across as shallow and glib. If you wade nto his comment section you'll regularly find commenters who are able to bring actual knowledge of the topic at hand and provide a far more prescient analysis than Matt.
I've read him for years, he's one of the few that have been in my reader since I began reading blogs in the summer of 2004 (TPM, Ezra, and Sully are the other stalwarts). I hate to be dismissive of someone who is obviously intelligent and writing to a broad audience from a prestigious perch but I'm just not getting anything value added out of the guy anymore. I read other generalists but those are more opinion or polemic than policy. Yglesias tries to be a policy generalist and it just doesn't work.
