a few months ago, my girls mom tried to explain to me, this is a made up language right?
all languages are made up.... and some literary standard languages (esp Basque, Slovenian) are very artificial combinations of different dialects.
Esperanto does have a relatively large wikipedia for the number of speakers (maybe 2 million)
And the duolingo Esperanto course in English has over a million learners
Polish International Radio used to do broadcasts in Esperanto (apparently they generated more mail than any of the other foreign language services ) but the program was axed by the first PiS government because of Zamenhof was a Jew (that's actually the reason that was given).
