I wonder how much more Amazon relies on written communication, over verbal. Even if teams are independent, they do interact with other Amazon teams, right? While there's always social value in some verbal and face-to-face time, it seems like if groups are independent, teams are gonna have to get good at writing things down, to avoid the madhouse.

I could have sworn I've read Amazon is notable for written communication, but I can't seem to quickly find the source. This seems like an important component of making small, independent teams work.
