The #amethyst street team approach has been wildly successful because you & your team do a great job of educating & informing users, as well as addressing problems when you can. Damus seems to have the same thing going on. I imagine as the user base grows that will become harder to keep up with.

Would a comprehensive user guide be helpful, as in one that addresses basic features, hidden features, and common faq? I started writing one then put it aside. I could finish that & link to issue reporting. I don't know if you would want to direct to that in-app but it could be an easy reference for the street team, especially if I can get a decent domain name.
