I just thought of a use case: book clubs. Specifically, a Book Brigade, where… UPDATE: Actually, lemme make that a top-level thread: Book Brigades!
So in terms of group goals, I’m thinking a handful of people share the goal to read a book and when it’s your turn to read a chapter or section, it’s also your responsibility to tell Beeminder the page number you’re on if it’s a beemergency. You’re also expected to take notes up to that page. When your section is done, you clean up and send those notes to the other groupies. (PS: Or a more live-blogging approach would be fine too.)
