I historically get so much value (and a bunch of FOMO, tbh) from HN book recs. Every so often somebody compiles a list of 'em, and here's the latest I've seen of that.
Obviously this indexes heavily on HN readers, but that's just fine for me. If you have zero interest in dev / math / science you may be bored, though.
I don't even need to write my own answer, because it's so similar to yours. The differences are minor: I stopped using Minds and Reddit, rather than X.
I also found SN very early in my bitcoin journey, so the stackers were a big influence on me diving in fully.
