As someone who is extremely supportive of the concept of creating a culture of written communication I have to say I've had a pretty hard time understanding why people think slack or other similar chat-style communication even qualifies. Don't get me wrong Slack is super useful, and I use it to communicate with my team all the time. But I don't think searching old chat messages is a good experience at all and I don't even think it even really qualifies as a solution to the concept in this article. To me a culture of written communication involves actually spending the necessary time to write down explanatory copy that helps inform other people. That could be things like comments in code, annotations or instructions for a commonly used document, detailed proposal or recommendation memos, FAQ's, guides to how processes work, and so on. There's this theory that this information already exists and the goal is to capture it. I'm not so sure, my suspicion is that you have to put in work to create it if you want to see real results.
