There's something going on with our spam filters. Please let me know on this thread if you try to post a comment on the daily blog post, but it doesn't come through - or it goes straight into moderation.
Comments will often go into moderation if you post a link in your comment. Potty mouth also goes into moderation, and so do users who have been blocked from the site. But other than that - your comment should go through.
Any problems?
