Ask HN: Async online book clubs focused on software/technical books?

I'm reading An Elegant Puzzle and want to discuss it with others who are reading it. I found https://onlinebookclub.org but after searching their forums for several well-known technical books (Mythical Man-Month, Elegant Puzzle, Phoenix Project, etc) I found no results.

I do not want something synchronous where everyone reads the same book at the same time, such as https://www.goodreads.com/group/show/131006-tech-book-club.

Does such a thing exist?
