I belong to two book clubs.
One I kind of manage. It's on meetup.com, but I have lots of help. We take it seriously, well as seriously as we can. We talk about the book for at least 30 minutes and we do our best to read the whole thing.
The other one is a 'honey badger' book club. We pick a book every month, but we spend MAYBE 3 minutes talking about it and no one cares if you read it or not.
I'm going to post all the books we have read. Someday.
