Some have asked how to post a comment on a blog. The secret is to click on the word "comments" which is circled in red above.
Then you pull down the "jump menu" and choose who you want to comment as. If you want to be anonymous... and/or you don't have a Google account, you can choose anonymous.
Then click Publish... and... your response will be deeply appreciated. I can't read your mind, so if you do have thoughts about something I've said, I'd love to hear them.
