I think this is an excellent idea but it seems like with something so complicated we might need a separate website dedicated to language learning/teaching. It is a shame to have so much skills and knowledge in the community but no easy way to access or manage it, which is why many people are creating groups on Discord or building their own websites. I am interested in perhaps collaborating and helping to work out how we can make this happen, since my previous attempts at a #polyglot tag also didn't quite work.
