Yeah, but you also like Mickey Kaus, so it's maybe just you have... unique tastes in punditry.
I don't read Wonkblog or whatever they're calling it, so I can't speak to how it's practiced over there, but I remember Elizabeth Warren's posts on the bankruptcy bill at TPM before she was a rock star, explaining (from a liberal perspective) the important features of the bill, the context of bankruptcy in America, and its likely effects. That was shit that traditional media wasn't even trying to do. The closest you'd get was a short op-ed, or a "straight" story with a couple quotes from both sides.
And yeah, it's pretty clear that you view all policy talk through the prism of a bunch of arrogant, pinheaded academics thinking they can rearrange the world to their liking, but that's similar to how I hear stuff about deregulation and privatization. Folks learn a bit of econ theory, maybe to the point where they can throw around terms like "price signals" and "deadweight loss" and suddenly they're comfortable applying a few basic rules based on some very stylized facts to industries and businesses in which they have absolutely no expertise or experience. I know, I know, deregulation isn't telling people what to do, it's letting people find their own solutions through the exchange of dispersed information, etc. but most of the folks pushing that stuff are as natural meddlers as anyone you'll find, and when someone says "it's ECON101" the buzzing sound in my ears gets louder.
