"#TheDress" is an interesting thing to think about because in itself, it doesn't matter. In 2015 it was a social, viral, publishing phenomenon. In 2021, at best, its the answer to a trivia quiz question in a loosely defined "the internet" category. Nobody really cares about it. (Except possibly that person who had the tattoo...)

But it tells us something about how people come together on the internet in a way that they didn’t just a few years previously. And that is something that does matter.
