Same here though I use Busuu. Used Duolingo in the past, to be fair there’s not that much difference between the two.
Been dreaming of a FOSS alternative, where people work together to make the best possible ever-improving courses, and all is free and customizable to your every need. That would be so awesome ! Surely some day some one will make this happen, right?
Personally I don’t murder because I don’t want to and I feel like it’s wrong to do so. Sure there are consequences, but I really don’t need them to stop me from going out murdering people. Perhaps there are people who do need these consequences, but it seems a fair statement to say that most don’t.
