This is cool—and now I’m trying to think of ways I can improve Indieweb.xyz for a purpose like this. One thing that comes to mind is possibly offering a few moderation tools for you. I think with a sub like this, it would be nice for you to have a “pinned post” or something at the top of /en/bookclub so that you can advertise the current selection for the club and some links to how to vote for the next selection—things like that. (This post would just be a syndicated post from your blog, Chris.)
