I really doubt more people speak Klingon than Esperanto – yes, I know I heard that factoid, but I suspect it was based on the idea that everybody who bought a copy of the “Klingon Dictionary” went on to learn Klingon rather than getting bored after page 3. The language is so (intentionally) convoluted that I suspect that no more than a handful of people really know the language rather than just being able use it to say “nuqneH”.
Plus, take a look at what’s been published in Klingon – a couple of translations of Shakespeare’s plays and one of Gilgamesh, and a stalled translation of the Bible. Esperanto has thousands of translated books and plays, the entire Bible and Koran, plus hundreds of original novels. That kind of suggests that there are a lot more fluent/near fluent Esperantists out there than Klingonists.
