I'm trying to get it fixed. I do use the comment moderation feature, but I normally clear and post them pretty quickly. If you see that it's not working, please shoot me an email!
So sorry for the screw up!
Update: It appears to be working now. Unfortunately all of the comments left while it wasn't working were lost. Booooooooooo.
Update 2: Things still don't seem to be working quite right. *sigh*
