Unwisely, I upgraded to MovableType 3.0, and have been having some troubles with comments recently. I’ll look into this and try to determine what the problem is. Thanks to Sue for pointing this out.
UPDATE: Problem solved. Just an embarassing PEBCAK that I don’t care to discuss. Apologies if it looked like you were banned from commenting on the site–it was a temporary gaffe on my part.
