A few weeks ago, I discovered private Slack groups for writers, engineers, artists — and almost every interest group you could imagine.<p>I thought about the significance of this discovery and why it was so shocking to me. <p>A few groups I have found:<p>1) A support group for startup CEO’s to talk about their struggles. <p>2) A private Slack group for the Bitcoin community.<p>3) A group for literature nerds who love talking about books.<p>I always thought of Slack as an enterprise product, and I never realized how many micro-communities like this exist. <p>If you're in a private Slack group, please add it to this list. I'm excited to see where the project goes!
