Cool! Please make sure to fix what I consider the major problem of Duolingo: it asks so much stupid questions (things I already know perfectly, even if I'm going to forget these tomorrow these still are nonsensical to repeat that much during the same session) I get bored and start clicking too fast so I make mistakes out of pure inattention and get even more stupid questions as the result.
Maybe your ideal way of learning or type of platform is different.
I have thought of experimenting with the possibility of having different way of presenting the same content. For example, instead of a repetitive software solution, exporting the course material as a printable book.
No. I like the repetition way (it works and it provides instant gratification to support the flow state unless repetition rate is t0o intense) and what I see in the current version of LibreLingo is ok. Just don't overdo. Or make repetition intensity configurable.
One way to distinguish mistakes of inattention from "actual" mistakes is to leave marking the mistakes to the user. So if you get inattentive, you simply forget to mark yourself wrong.
My personal system works that way; though not for any particularly clever reason. I just have no idea how to automate the checks. I don't recommend anyone to try it unless you want to spend a few hours setting it up, but there's a screenshot in the README: https://github.com/Yorwba/alphabet-soup
Looks interesting but you should really ad a European language. I'm looking forward to learn Japanese and Mandarin once but don't feel like doing it right now and I probably am not alone. The LibreLingo author has made quite a wise decision to choose Spanish for the example language - it's the easiest and makes a lot sense for everybody to learn (given how many countries use it).
Well, I've chosen Japanese because I'm learning it. I'm not really looking for users right now, I just thought others might find some inspiration in what I'm doing.
