How is Duolingo funded? I just can't work it out...
How is a free program the best, funnest and easiest platform I have ever tried to learn a language on. Someone please explain:
Do a search on "Luís von Ahn." Every time you use a captcha or recaptcha to let a web page know that you're a human being and not a bot, you're using his technology.
That does pretty much explain it. I've posted that on my wall as yet another attempt to make to people start it
