For me, the green berdie trying to put you in its basement because you forgot to do your French lesson is more like a meme than an app I use to become fluent in a language. I see how hyped up it is, and their ads are cool, let's give them that. Although I still can't take Duolingo seriously, mostly because it feels like they're just giving you the illusion that you're studying something, when, in reality, it will take you a decade to get to B1 level just doing one lesson a day on there. So, what do y'all think?
Update: I've realized that it's better to clarify some things so here I am. I'm not saying Duolingo is useless, it's just that I myself prefer to learn languages 'the boring' way, with textbooks and everything. I also feel like there are better apps out there that might actually help you better with your goals, whichever they are. Additionally, I do realize that five minutes a day is not enough to learn a language, but I've met many people who were disappointed in their results after spending time on Duolingo. Like, a lot of time. Everyone is different, ways to learn languages are different, please let's respect each other!
