Interesting how having intellectual curiosity as the goal, rather than the ubiquitous 'an inclusive space where everyone can feel safe', has ended up in a forum that's much 'safer' and less toxic than most places on the Internet.
Most of the norms of spaces that are deliberately inclusive are norms here too, but they're common law norms: they're stated very generally in the guidelines, but the real binding norms are in Dan's comments.
