The upside is that there is a good deal of great dancing going on in many places. But some couples look like clones of one another. In this subculture, dancers often take classes every week. They hold socials where no alcohol is served. It becomes much more athletic, more exciting, and you want to do that with people who dance at your level.
Good looks are no longer enough to entice a man across the dance floor.
And, of course, dancers, can dance both styles. Some call it more authentic. To me, on the 1 is for only listening to the top layer of the music. It's more melodic. But the dancing on the 2 is really on the African beat.
