If you are on Google + you can comment with a minimum of difficulty, and we get to see your avatar. If you are not a Googlonian, or do not wish to reveal your mane, I *have heard* that you can sign in as a guest.
One advantage of a blog is that the blogger gets to engage the audience. So comments are important to me. Comment away! Please.
I am working to see if there is a way to facilitate comments, but Google+ is a work in progress. Tomorrow may bring a solution we do not have now.
