Ask HN: What's your favorite online course?
Duolingo: <a href="https://www.duolingo.com/" rel="nofollow">https://www.duolingo.com/</a><p>It's not tech-related, but I have achieved near-fluency in one language in less than a year (Dutch), and I'm currently learning 3-4 others. (Russian, German, French, Italian) I find it very effective and easy to fit in around everyday life.<p>I would definitely recommend it to anyone else seeking to learn languages.
