I'm trying to understand how #slack works. (Yes, I know it's electron, inefficient, and non-FOSS, but I have to use it with a new organization.)
I've heard it described as email but less asynchronous, because it pulls in instant messaging features. And I've heard it described as email but *more* asynchronous because it doesn't push notifications unless you @ someone.
So, which is it? Or both/neither?
What do I need to know coming to Slack from email?
