So some news items on Esperanto.
On DuoLingo, Esperanto for English Speakers is up to 939,000 learners. That's pretty huge... just under 500,000 in less than a year, and approaching a million users at less than the year-and-a-half mark.
Esperanto for Spanish Speakers is now launched, and is up to 164,000 learners.
That means that on DuoLingo, you've got 1,104,000 people learning Esperanto! That's pretty cool! Granted, some of those might be "inactive", like we see happen with a local religious organization - they are still counted on the books, but are no longer practicing. But that's still pretty darn cool, given that the number of people that speak Esperanto frequently worldwide is estimated to be at 2 million or less.
Also, a fun article from a renowned Polyglot about Esperanto, and why he highly recommends everyone study it:
