How much can Duolingo teach us?
I'm the pro Duolingo user. I used to pick up new languages just for fun. It did help me a bit when conversing with uber drivers in Spanish, but I was stumped when i completed the Japanese course.<p>I could quickly, and effectively go through the course with no hurdles. But then my sister asked me to count to ten in Japanese. I know the words, I can complete a challenge that include numbers, but I could not count to ten in the real world in Japanese. Duolingo banked on the gamification, and that works really well. However, learning a language is only incidental.<p>I wrote an article about it and received threats to take it down. From time to time, i get a hoard of emails calling me toxic and threatening to sue. It's still up if you can find it.
