@sputniakmusic @librelingo i would love to see a different approach than duolingo. Although i love the idea of a FOSS alternative, just learning words and sentences, is not really helpful. After 1500+ days streak learning spanish with duolingo, i still can't make a conversation that is more than basic in spanish (and i'm Italian, so i can understand some spanish without studying it).
This could be useful just to practices and learn new words. But i would love to see more grammar lessons!!
