Fair question and good point. Our Slack isn’t absolutely quiet - we do have a channel for coordinating on customer issues (meets our urgent and ephemeral criteria) and it might be that some matters are raised by other processes outside of Slack but Slack itself is a good fit for in-the-moment collaboration. But in short we aren’t absolutists, it’s a mix of a few specific channels for certain contexts, channel-specific muting, and updating one’s Slack status - all under the guidance that Slack immediate responsiveness is not generally expected but more the exception. It sounds like a lot as I write that, but as a broader cultural norm within the company it does (so far!) support itself.

That said, I’ll pass your question on to the team as feedback, we should make the answer more clear.
