Comment moderation has now been enabled (both manual and through Akismet).

Hopefully this will put a stop to the comment spam. Tip: Post your comments as a logged-in user. This lets them show up right away (although they will still be processed by Akismet after a few minutes).

Update: It looks like I failed to set some database permissions properly, and adding new comments was failing. I thought it seemed a little too quiet around here...
