If you're wondering where the action is lately - it's down in the comments sections of the recent redistricting, Rose Institute posts. There will be more posted material soon as well, but in the meantime, have fun with the banter.
Update: No really, this post has 19 comments. And they aren't short. We haven't seen audience participation like this since caption contest days (entries for which were tragically lost in the great comments-server fall of '05). Granted, it's mainly a back-and-forth, but still. Yikes!
