I received an email today from a friend who indicated he had wanted to comment on one of the posts in TYWKIWDBI, but didn't want to create a "Blogger/Google account." That is not required.
To leave a comment, click on the "comment" feature below an entry; the webhost offers to let people sign in using their Blogger or Google identities, but it is not necessary to have or to create one. Just write your comments, then scroll down to "anonymous", check that, and click on the "publish comment" command.
I do "moderate" (screen) the comments, but that is only to delete spam, profanities, and inanities; I don't screen out conflicting opinions. Your comment should show up within a day (whenever I check the blog).
