Hunh. It feels weird to say "Language learning apps are always ugly, clunky" and "Apps only ever support the major languages, leaving minority languages in the dust" when those are a few things that Duolingo actually does fairly well. Don't get me wrong, Duolingo has a LOT of flaws and I'm excited to hear you're building an alternative to it, just the pitch feels like it's based on a time when Rosetta was the name to beat.
