It's been a few days now and I'm going to stop posting about #NBPy soon but I do want to stress this before I do. I've mentioned that the event is pretty special, but it's hard to succinctly articulate why in a direct way. As a way of gesturing at what I mean though, consider that this is an event where the organizer can get up *after the conference is over*, say "it would help us if some of you could pay more for your tickets" and a bunch of the audience *does that*
