I see that my response to this has been rudely disturbed by a pandemic. I actually dance a lot at my own milonga, leading by example so to speak, pun intended. Of course, I try to enroll as many leaders in the same mission to give everybody a good time which over time has been successful, creating some critical mass of leaders willing to contribute to the bigger cause next to the ones that are more selective, which is also totally okay. As for the outsider part, your strategy is also very useful for me. I wrote a piece on our primate roots that sort of explains the background of it, purely in the interest of science of course 🙂
