Two issues at hand today:
1) If you try to post a comment and it doesn’t appear, let me know. Several things could have happened — spam-filtering being the most obvious. Occasionally I delete comments because they’re really stupid, but that happens only rarely.
2) If you use HTML in your comments — which I allow — please check your tags before you publish. For want of a tag, a thread is lost, or at least screwed up.
That said, Laura, I think I deleted your comment. I thought de-spamming it would make it post, but I guess not. Then I deleted the whole spam file and pfft. Sorry.
