Brian Leiter's got an interesting post on why he doesn't value civility when it comes to blogging (what makes it personally interesting is that Brian has been unfailingly civil to me in personal contacts). Orin Kerr replies with a defense of civility. Personally, I prefer a civil tone (not that I always manage to achieve it; cf. Romans 3:23), but I nevertheless appreciate Brian's biting acerbity in much the same way I enjoy Mencken's acerbic wit and sarcastic tone. It takes all kinds to make a blogosphere, after all. But, of course, your mileage may vary.
