As of now, all new comments hit the moderation queue. However, you can bypass the need for me to approve your comment. When you submit a comment, my system will send you a small email to the email address you supplied. If you click the link in that email message, it’ll approve the comment right away.

Interesting implementation, I’ll be interested to see his idea for lessening the burden on folks that have already clicked through to confirm previous comments (discussion in comments).
