I found your newsletter article through Mastodon - good post. I was inspired to comment because I also use a Guestbook in lieu of comments. What I never did, however, was include a field at the bottom of every article explaining that the Guestbook is there for comments, among other things. Unsurprisingly, it has been very seldom-used. Your design concept made me feel very dumb, but it also inspired me to add my own field at the end of every post explaining that people who are interested can comment in the Guestbook.

Now, I hope that I will get some comments that are about my site instead of cheap amoxicillin or dating sites. Thank you much for the idea.
