>listen to linguist McWhorter explaining that people should think of texting (or Slack) as "transcribed informal speech" -- instead of formal writing.[1] I can't watch the video right now, but even in informal speech, I hear periods and commas. I think that those are necessary for communication. Not including them, as I mention in another comment above (or below?), induces a cognitive load on the reader. Nobody should be asking for perfection on Slack, but mostly correct should be the bar.
