It was brought to my attention that no comments were being posted. They have since been published, all 47 of them!
The problem was that Google normally sends an email that informs me that a comment has been sent and which allows me to read it to determine if it is appropriate to post to the blog. Some, frankly, are not.
If any of the recent comments are upsetting in any way, it is because they were not monitored in this fashion.
I will try to determine why the Google Blogger system changed without notice and will monitor new comments via my "dashboard."
