L.L. Zamenhof, Inventor of Esperanto, Honored in Google Doodle

Thanks for a thoughtful piece on Esperanto.  Just a couple of things I'd like to call out. Ironically, Google offers search results in Esperanto. I'm guessing you meant to use a word other than "ironically".  If, however, you actually did intend to use that word, I'm curious to know how it's ironic.  If, by "search results in Esperanto", you're referring to the Esperanto user interface, Esperanto is far from the smallest language for which Google offers a user interface.  If you're referring to the Esperanto language filter, a quick Google search for "Esperanto" returns millions of pages.  There are plenty of things Esperanto to find on the Web (supply), and plenty of people to search for them (demand). Although the language was not universally adopted, it was spoken by nearly two million people at one point. It is still widely used in correspondence, conventions, broadcasting, and military. Your phrasing makes it sound like Esperanto peaked a while back, and is now on a slow decline, even though it has not fallen into oblivion yet.  If anything, in recent years, Esperanto has been growing robustly.  Esperanto owes a large part of its growth of late to the Internet, which has made Esperanto resources available and brought Esperanto speakers together like never before.  The two-million-speaker figure you mention dates back to the late 1990's / early 2000's, when the Internet was already well established, so Esperanto can only have grown since then.  A better reflection of the modern reality of Esperanto would have been: "Although the language is not universally adopted, it is spoken by some two million people and growing. It is now widely used in correspondence, conventions and broadcasting, and various facets of day-to-day life."  (I'm not sure about the "military" part, although at one point, the U.S. army did use Esperanto in combat simulations to represent some foreign agressor's language).
