When you mentioned the set of "cosmopolitan libertarian metrosexual econophilosopher bloggers" I assume you meant to use a definite descriptor to pick out only one particular: you.
An interesting question is whether there are any others. If you drop 'metrosexual' then you can include lots of GMU guys. But Hanson, Kling, Caplan, Cowen, Tabbarok, Boettke, etc. are far from metro.
You know what? Are you really metro? Because you seem more nerdy than metro. I guess I think they're sort of mutually exclusive.
