Chances are...probably not. But a lot of people do. According to the Guinness Book of World Records, it's the most spoken fictional language by number of speakers. It has its own institute , and one of its characters was used in the original Wikipedia logo. And alas, most people are unaware.
Most people aren't concerned with what moves us, bothers us, attracts us or inspires us. Most people don't have an iPhone, a car or speak English. Most people don't do things like we do. But, some people do. Some people believe precisely what we believe. Some people care about things just like we do. Some people want to go where we're going.
Too often, when we set out to spread an idea or change something, we scale too big. We think most people in our world, city, company or department will surely be interested. But, what if we're trying to teach them a new language, likely one they've never heard of? It's hard to gain traction with a disinterested audience. Better to find someone who enjoys the movie as much as we do. They might just help us find a few more.
