I would like to learn a couple of languages (polish and Japanese - I already learned Spanish to a decent degree) but it seems like every solution is closed source.
I would use books but listening (and speaking) are very important and books won’t help with those.
What would you guys recommend?
I think who one gives that information to matters. I have chosen to give that to my non-profit VPN host, people who doesn’t know will never have the chance to chose. I think that’s important. Goodbye.
