1. Newsletters. One basic example is Bitcoin Optech. I've always been the kind of person who looks at any newsletter just about long enough to put it in Trash. But I've come to understand there are plenty of greatly curated and/or written ones out there.
2. Podcasts. I can recommend Unconfirmed and Zero Knowledge, for example.
3. Discord (I know I miss out by not going here but the noise-to-signal ration and complete lack of privacy/anonymity/anything like that are both too much. It makes me a bit sad that this is where the action is even for infrastructure and supposedly open/freedom-asserting projects.)
Can be non-trivial to find the good ones for whatever angle/topic you are interested in, of course.

Absolutely agree and I couldn't agree more with the comment you're replying to.
