> how Duolingo started using streaks and other gamification techniques to optimize their numbers
These two tactics per se are alright, right? If anything, I'd appreciate that Duolingo tries to keep me engaged. Besides, the more one spends time on learning language, the faster they learn.
The issue with Duolingo is not about gamification, but that translation is ineffective and boring, no matter how much gamification there is. Personally I find that the most effective way to learn a new language is starting with Comprehensible Input and then moving on with tons of output. Take Spanish for example, Easy Spanish, Dreaming in Spanish, Español Sí!, Extra, and Destinos offers lots of fun input for beginners. Paco Ardit's graded readers are great too.
Another problem with Duolingo is that it does not help listening comprehension at all. It turns out that we can only pick up sounds in context with tons of repetitions and combinations in consecutive sentences - a feature that is exactly what Duolingo misses. Yes, it has introduced listening and stories, but the amount of them is too little to be useful. Another lesson is that reading does not help improving listening much. When we read, we see individual words and phrases easily, while it's really hard to pick up individual words when listening. I didn't understand the difference and spent a lot more time reading than listening. As a result, my reading was at the level C1 yet I could only understand slow Spanish at the level of A2.
