I find it's easy to scroll past very sloppy posts. And 1 in 2 posts are genuinely interesting/teach me something new about the world and the people in it - how people conduct business - and most of all their improbable trajectories that got them where they are currently in their career. It's very interesting and the recommendations are great for me. I don't find too much slop or cringe content, and am confused when people complain about it so much. It feels like people don't really know how to separate slop content (self-promotion/empty AI posts) from genuinely written life and work experiences. And HN is definitely an echo-chamber, I see a huge amount of people (more than instagram tbh in mid-30s age bracket) contribute regularly to linkedin.
