The most important thing to me about the original diagram is that it is underspecified-- you can't determine its meaning just by reading it and also having a basic knowledge of Slack. To understand it you need a close and detailed knowledge of Slack UI and behavior that I don't believe has been officially documented. In fact, I'm left with questions about this diagram I can't answer even after experimenting with Slack. In other words, there is important tacit knowledge required to interpret the logic. I wonder if there is an updated version of this available anywhere?
