Would this be you discussing the books and allowing for comments underneath? Or would you be discussing various books with other people?
I don't know if you have seen Mark Reads
? He hasn't ever read the books before, but he is working his way through them in order. The videos get posted to YouTube and he posts comments about each section as he reads them. I suspect this isn't what you are planning, but you might get some ideas from them.
Good luck! I'd certainly watch them and would join in any discussions.
