I’d say that that huh is the foundational block of curiosity. To get good at the huh is to get good at both paying attention and nurturing compassion; if you don’t notice, you can’t give a shit. But the huh is only half the equation. You gotta go huh, alright — the “alright,” the follow-up, the openness to what comes next is where the cascade lives. It’s the sometimes-sardonic, sometimes-optimistic engine driving the next huh and so on and so forth.
Form comes from wonder. Wonder stems from our 'in touchness' with how we were made. One senses that nature records the process of what it makes, so that in what it makes there is also the records of how it was made. In touch with this record we are in wonder. This wonder gives rise to knowledge. But knowledge is related to other knowledge and this relation gives a sense of order, a sense of how they inter-relate in a harmony that makes all things exist. From knowledge to sense of order we then wink at wonder and say How am I doing, wonder?
Publish a list of books they would be willing to discuss with other people to the open web. Antilibraries – collections of books you haven't read yet but would like to read – are particularly well suited to this proposition.
See which books people in their social network want to discuss, and/or subscribe to other people's lists
Be notified when 4+ people in their network have the same book on their discussion list – possibly via an email thread?
Coordinate and schedule a time to read and discuss the book with that group.
