Historically - like, way back - a lot of the Ruby core chatter happened on a japanese mailing list, and that's where a lot of decisions ended up taking place, or it wasn't uncommon to have sudden hard subjects bombdrop on the english side while a lot of discussion already happened on the mailing list already so it was hard to catch up.

These days it seems like bugs.ruby-lang.org has most of the chatter.
