Slack (and teams, discord, skype) are all antithetical to the style of written communication outlined in the slide deck. They make difficult writing a long, well-structured document to record and transmit a complex idea. IM team coordination platforms are only good for the first phase of writing, that is, just getting ideas down in written format. The issue is that the tools built into those platforms do not aid in the other phases of the writing process, and in fact, they sort of make it difficult, actually. I speak from experience having to go back through thousands of Discord messages to condense the ideas into a collection of documents on different topics.
Someone should write an extension that makes it easier to convert IM thread to an organized document outline in slack or discord. That would be nice.
