Search at Slack
Slack is great, but it's adoption by popular opensource communities is problematic.<p>Why? Because opensource communities are on the free plan, which limits search once you have 10k messages. I've had experiences where I wanted to revisit a question I had asked in a Slack channel the previous week, and been unable to find it.<p>As a result, everyone burns out faster b/c the same questions get asked and answered over, and over.<p>Couple this with the fact that channels are not indexed by Google and you get a black box where valuable Q&A content and discussion goes to die.
