I saw this at Aziz's blog and I signed up. It is something of an empty gesture for me because I rarely get into the personal disputes with other bloggers, though this was more semi-common in the first few years of this weblog's existence. But who knows, if there was more tension about the Wright-Fisher controversies perhaps I'd be getting down & dirty too. But I'm all for people behaving less like animals, so I signed up (OK, I mean emotional animals, something sedate like a ground sloth is tolerable because it is ignorable).
