Pros
On the cultivation of values and an intelligent atmosphere, sort of a rising tide lifts all boats situation. I've learned a lot in a short while from peers and the massive handbook that records many scenarios for future teaching. Benefits are terrific, work/life balance is more than lip service, and people are happy to help. Interesting, cutting edge.
Cons
One could get lost in the bog of slack channels, issues, DMs and other communication tools. There at once seems to be a right way to present ideas and send messages, and yet there still seems to be a divide in what's sanctioned and what's practiced. People will happily teach you things, but the culture of self-learning sometimes makes it a last resort. Transparency and everyone can contribute should have boundaries.
