> Writing messages on Slack isn’t what engineers get paid for, though. Writing code to solve problems is. Instant messaging tools are seen more as a necessary evil to get work done in a team than anything else. Because of this dynamic, there is a tendency to elide details or cut messages short, sometimes at the expense of legibility.

The article is long on tips for individual media without explaining why you'd use one over the other. Digital communication encompasses a wide spectrum of media, each with its best use:

- realtime/recorded text (Slack, GitHub issue, README, Comment, etc.);

- recorded graphics/text (PowerPoint)

- realtime/recorded voice (voicemail, phone);

- realtime/recorded video (Zoom, YouTube).

The most important question before you use any one of them is: why this medium and not one of the others?

Even the right message created well will flop if sent across the wrong medium.
