That’s what happens when you have some of the best user experience people and engineers in the world specifically designing for addiction. Facebook is no different, but their most successful demographic is. My grandma is hopelessly addicted to scrolling FB reels and my fiancé is hopelessly addicted to scrolling IG stories. Different target demographic, same goals
It depends on the language tbh. Several languages on duolingo are decent ways to dip your toes in the water for language learning, I've heard good things about the Spanish, German, and Mandarin courses.
But it's really dependent on the language, I tried Duolingo's Irish course and it was so bad that I'm still trying to unlearn a good amount of misinformation, really soured language learning for me even though I eventually got a good course elsewhere.
I did both the Spanish and French trees completely, I do think I learned some things along the way, and some of it stuck. Every language learning method is not perfect, you need to immerse with multiple things. I was living in country, doing duolingo, listening to pimsleur, listening to radio in language, going to classes and hanging out with native speakers, and my fluency still is not great. It takes years of being a child before you get anywhere and no system is going to solve it alone
Honestly I had that app on my phone for 3 months before I actually started using so I feel you there. It's not that bad to start off with and it starts super slow. And fuck streaks and notifications and all that shit I just do it when I'm bored instead of scrolling and refreshing pages on my social media of choice.
I'm highly suspicious of Rednote. It came out of nowhere with a sudden, massive surge in downloads, so tiktok users assume that's where refugees are flocking.
