> have some ideas about what works for language learners that is not expressed by language learners experts.
This seems like a culture clash. In programming blogging, it is completely fine to write blog posts about the mental model that works for you (as long as it doesn't contradict evidence) and then maybe it works for somebody else. The idea that I need to first get an approval from a commission of Serious Teachers That Verified Which Approaches Work Well For Learners Statistically is laughable to me.
I write for myself and for people like me, period. I do not claim this is useful to anyone but a tiny group. This tiny group is who it's written for. I explicitly say in the article that I struggled and this is what got me unstuck. If it isn't helpful, just close the tab.
I think you may be spot on about the culture clash. Language learning takes a long time, and there are really no short-cuts nor magic solutions that will get you from zero to competent within any reasonable amount of time. This is in stark contrast with programming. If you already know a programming language, you can get reasonably acquainted with your second one by following a really good tutorial in a single afternoon (depending on the languages though).
This make a lot of language learners (including my self) extremely vary and reactive of tutorials and explainers such as these. In the language learning space, tutorials belong as chapters in a good textbook, and explainers belong in dedicated sites written by teachers who have proven their worth with dozens of other explainers (e.g. https://www.tofugu.com/). The difference is that these are meant as part of a much much much longer journey.
[Aside]: Japanese is actually my 5th language and the first that is self taught and outside the language environment. I am also a self taught programmer. I have observed that learning Japanese is in a totally different league then any programming language. I am now two years into learning Japanese, and I can barely read a kids book, and no way can I hold a conversation. At this point in my programming journey I was already writing three programming languages fluently (JavaScript, Python, and R) and was learning the 4th and 5th at the same time (Rust and Julia).
[Re: “this is what got me unstuck”]: It is quite common in the language learning space to learn things intuitively by mere exposure. And sometimes a language learner will falsely attribute some (what appears to them as a) novel approach to what got them unstuck, but what really happened is that just engaging with the language reinforced old neural pathways and they just suddenly “got it”, the novel approach could have been anything, what mattered was the engagement, not the technique. This is also true in programming, but in language learning it is extremely common. Our brains are wired to learn natural languages, and given enough exposure to the language we will learn it.
