This has happened before and I know not the reason why but it has happened again. Some people submitted some comments for posting, I clicked to post them, and then the comments went off into the cosmos.
Sometimes, the comments eventually show up, but if yours do not, please resubmit them. I only reject comments that are spam, defamatory, or in poor taste. Of those, 99 percent are spam. You'd be amazed at how much spam comes in the form of comments. Although it has tapered off lately, I'd sometimes get 25 or more spam comments completely unrelated to the post. Most sold gold.
I apologize for the inconvenience.
