> isn't social, it's a performance for an invisible audience.

I know what you wrote is fairly obvious but the wording really resonated with how I feel about social media platforms but couldn't quite word it so well.

When I was young (a long long time ago), my family would go up to stay at a ranch in Sierra County California. They had almost no TV or radio reception there -- you still can't get a cell signal at my cousins house. They would have a Friday night square dance that was like a school dance that teens actually attended and danced together, without much irony. Coming from San Francisco it seemed a little weird, even then. It seems so old fashioned now but I really treasure that I got to participate in what people used to do on the western frontier of the US.

Dancing is fun.

My wife was maid of honor (we weren't married yet) at her college roommate's wedding. I danced with several of their friends at the reception; one taught me to two-step (it was in San Antonio). I taught her basic swing. There was exactly zero romantic involvement; I was there with my girlfriend, for heaven's sake. But she was nice, she was fun, and we just chatted as we went through the dances. Got a couple of her funny college stories out of that. And that's what it's about: having an excuse to be physically close to someone else, doing an enjoyable activity that rewards skill, and to gossip a little. We, like all apes, are social animals. We're happier when we do that.

I agree but would like to point out that I have seen several groups of dancers practicing K-pop dance or something I don't know outside of Sydney convention center recently. So it seems there is still a social circle where people dance but not ballroom or salsa.

And in 20 or so years people will lament the loss of dancing to an invisible but captivated audience, I'm sure, just like they currently lament the loss of Vine and Myspace.
