Comment spam has become a real problem, so we’ve enabled more aggressive auto-filtering. If you think your comment was marked as spam erroneously, email me.
If you want to avoid the spam-detection stuff altogether, comment here using a registered identity from TypePad, OpenID, Google, Yahoo, AIM, or WordPress.com.
It is likely that we’ll go to authenticated-only for comments in the near future. Sorry, but Heathen’s notched 156,000 spam comments in the last two weeks alone, no word of it a lie.
