We currently have 2 books on the go, and as one ends another is starting up, which, if I remember rightly, takes us into January. So it strikes me that there is already plenty to read. Plus, of course, we also have all the old clubs which people can still add to.
My personal opinion (not an argument or something I want to debate, just my opinion) is that the best way to start a club now is just as にゃんにゃん1 and にゃんにゃん２ were started, by someone keen to read the book and committed to see it through, without all the fuss of polls and debates and discussions.
(And if anyone is interested, I’m reading a Gundam manga like that starting on January the first!)
