all good tips!!

you can get by with a small amount of grammar. For most languages. This goes contrary to what is often thought in schools, I believe.

This is my experience too! start with essential words with basic grammar, then pick up more words along the way, and keep speaking.

I used to run a language learning blog with more useful, language-specific tidbits, but sharing it would probably doxx me.

This. I secretly think many stackers are good at something, but they're too shy to share it or afraid it might dox themselves.
