So it would seem that at some point, maybe a year or more ago, something changed in the "Blogger" software I use for this blog.
I was no longer getting notification of comments waiting to be approved for publishing on the blog.
Today while poking around trying to solve another problem I found all the comments, and have only just now "approved" them all and they are up on the blog now.
So I'm sorry if you felt ignored or otherwise slighted. Just me being ignorant of the nuances of the software.
