One of the things I felt in my time guestblogging for Ezra was the way new environments reshape the way you write. It wasn't just a question of trying to write for Ezra's audience -- an audience which I take to be quite interested in arguments that advance the debate on substantive policy issues, as opposed to partisan rah-rahing or goofing around. (My Robby Gordon mockery was the only real departure, I think.) To a certain extent, Ezra's own past output constrained my output, and I felt some need to make my posts fit with his in style as well as content. This was a very good thing, since he's an excellent writer and I can profitably move in his direction.
I look forward to the time when Matt gets entirely comfortable writing in the Matt-style at TPMCafe -- I don't think it's happened yet. I think he's entirely comfortable on TAPPED:
My friend Julian Sanchez wrote a defense of judicial review for Reason a little while back that I also think is worth reading. The thing about Julian, though, is that he's a libertarian and Reason is a libertarian magazine. If I, like him, subscribed to a morally bankrupt fringe ideology I, too, would be a judicial review enthusiast because fundamentally (in the common-law context) it's a libertarian institution providing an additional check against government activism in all spheres.
I can see how writing at TPMCafe could shift your style in odd ways. He's in a new place with a whole bunch of heavy hitters. I wouldn't have thought of this before the guestblogging experience, but now I see it. (I hope the new typeface he's got at TPMCafe isn't swaying my opinion. I associate Matt pretty strongly with Arial, not TNR, and there could be some weirdness going on there.)
Update: Now I'm really worried that it's just the typeface.
