I think the other side of this is that some folks tend toward perfectionism in their writing, so in an atmosphere where writing standards are perceived as very high, people can spend way too much time and energy trying to put things in just the right way, when they otherwise could have gotten their ideas across in a few seconds using a "stream-of-consciousness" style that is more similar to casual conversation. It can become a huge time sink.

Also, if people feel like casual or "sloppy" communication will be judged negatively, they might often choose to say nothing at all instead of sharing half-baked ideas, which probably reduces organic creativity and innovation, even if it leads to fewer interruptions.

So while I get the point this post is making, there are costs on both sides here. And some of the worst downsides of the casual style (interruptions, in particular) can be minimized by adding more structure around sync vs. async communication, protected focus time, and using different mediums when appropriate.

People should go for the middle ground on Slack. If you miss a period, so what? But skipping all of them just to be "casual"? That induces a cognitive load on your reader that you shouldn't.
