I've noticed this too. In a way it's sort of a resurgence from the 2000s when independently-run forums ruled the day, but there's a different flavor to it because they tend to grow more from word of mouth. Slack groups not being indexed in Google search is surely part of that. This is generally seen as a feature, though, not a bug.
