There's already a distinct self-segregation in milongas. I'm not talking about elites/non-elites, styles, ages, et cetera. People who take tango seriously, for some definition of serious, and people who treat it as just another leisure activity. Almost everyone starts in the latter, but only a few who stay in tango and actively work to improve their tango even outside of milongas and prácticas and classes — I don't include people who just go to classes and workshops, because they're plebs and most of them are just class-goers — move to the former category. There is this sense of they just don't get it that separates the former from the latter. And it's telling how one group moves independently of the other, with only an occasional interaction.
