Tyler and Alex want to "dominate the market in econ blogs."
When an industrial organization economist reads such a statement--O.K., maybe not all industrial organization economists, but at least this one--he asks: "How do you define the market?" I first thought, "Economists who blog regularly about a wide range of topics from an economic perspective." On second thought, that definition has problems. (Market definitions usually do.) Should econoblogs be restricted to just "economists"? What's a "blog," anyway? How often is "regularly"? Should the definition include blogs that specialize in just one area of economics, such as taxes, international economics, neuroeconomics, oligopolies? What about some of the fine public policy blogs?
On third thought, since the antitrust authorities aren't suing Alex and Tyler yet--but Institutional Economics cracks, "It is just as well Marginal Revolution are only intellectual entrepreneurs. Commercial entrepreneurs would be setting themselves up for anti-trust action were they to put in writing their intention to dominate a market"--there's no need to overthink this. At least not unless readers express interest, and readers offer to help, and someone provides major, major financial support. I'll just note 20 other blogs--one is actually a list of links to blog posts, a list that changes weekly-- that I think would probably belong in the market and that I think are worth a look.
The first four are already listed in Tyler and Alex's links and are probably the dominant oligopolists in the market. I especially recommend EconLog, by Arnold Kling. It is consistently interesting, thoughtful, and free of cant.
