My main issue with the 1 post per month thing is that as I got older, I really only reply to things that are relevant. I'm active in the discord, and people know I'm around, but there isn't always a "topic of interest" to post on here.
I looked at the book thread, but it's only a couple posts long with the last response being in August. We do a lot of stuff on the Regional board, but it might be worth bringing some of those topics here at the same time.
