a thought on work chat systems... the best "chat" tools and cultures:
- encourage and default to shared, topical channels
- channels are *public and discoverable* unless they absolutely have to be private
- DMs are rare
I've anecdotally observed this over the course of my career where I've worked remotely since '08
a well moderated channel with hundreds (sometimes thousands) of people is infinitely better than the asymmetry produced with an unbounded number of ad-hoc DM's
