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.
What the other commenters said, but if there was drama it’d probably be due to the fact that deadmau5 used to be one of the biggest assholes in EDM. He might be nicer now, but back in the day I’d never heard of someone having a pleasant interaction with him.
