If everyone's talking asynchronously, why not use email?

[nottorp]

- talking async is a lot less friction than sending emails

- you have your info pre separated in channels instead of needing to sort your emails into folders

- you can pin important data to the channel for future reference

- even sending small files is less complicated via a chat app

- you can get up to date just by scrolling up a bit

That's all I could think of in 2 minutes.
