Same. At first I was skeptical but whereas HN, Lobsters, etc are mostly baseless opining (mine included) and hot takes, there are discords where they have more signal than the infotainment I enjoy on HN. I’m in a few where people regularly group-read research papers, help each other understand them, etc. I enjoy HN very much, and I still feel uneasy about the ephemeral format of chat, walled gardens and all that, but the content is refreshing.
