Esther Schor tells us the story of how Esperanto was invented. It sounds like an interesting idea on paper but in my 57.9 years on this planet, I don't think I've ever heard a single word uttered in Esperanto. The only person I ever met who I knew had studied it was Forrest J Ackerman and when I asked him who he could converse with in that language, he said, "Well, every so often I attend a conference of people who are trying to promote Esperanto and we speak a little of it there."
