I ponder a lot about community and how important local community is for the functioning of society; many are the riches brought from afar by long distance communication. Nonetheless, local rationality meetups can increase local metis by generating intelligent community. I read in Isaacson’s biography of Benjamin Franklin how he (Franklin) employed his Junto to advance scientific knowledge, civil society, and business; there are some great examples there. But the Wikipedia page will do well enough for an overview.

What I have done here is taken the Junto discussion questions of Franklin's club and reformulated them to serve as a model for the types of questions we can be asking each other to keep advancing community and local knowledge.
