Tyler, I have been thinking of something similar -- personally I love to read money/finance/business related books. There are lots of great books out there but no modern way to discuss about them. I'm not a developer but certainly your idea sounds good. The system has to be interactive enough, which should be quite easy to achieve nowadays. FB and Google hangouts sound like a great combo. I'm afraid there has to be a substantial amount of HR (people who drive the discussion), otherwise the activity will die soon.
