>Stuff spoken in person is imprecise, secretive and easily forgotten. Slack is clear, persistent, and public.
I don't get how verbal stuff is imprecise but slack is clear. I find it to be the opposite. It's much better to have a face-to-face chat or a voice chat than converse in writing. It's more clear and you can get more feedback from the other person. Also, if you need to be more precise, you can just write stuff on a board/notepad/chat while talking.
When you talk to people, they're more likely to support their assertions by citing sources with precision than when they write? Really? When I talk to people, I get a lot of "I read somewhere that X is true" and "I heard from someone that Y is true". And when I request sources, they say they'll get back to me, but they rarely do.
Anything that is is written down tends to have less hand-waviness and bullshit than the random spew that comes out of people's mouths when they are making up their ideas as they go along.
