So been here slightly longer and the only shift I can recall is a shift away from business to tech.
Early days had a lot more discussion about the business side of startups and vc. Then it started shifting more towards tech too the point now where startup/business discussion is mostly limited to Show/Ask posts.
The loss of chatter around the soft skills around tech (so business but also UI/UX design, design patterns, organizational approaches (like holocracy), planning processes, etc) has made HN a lot less interesting IMO. If I just wanted the usual tinfoil hat FOSS BOFH content, then I can go literally anywhere else. Reddit, Matrix, IRC, Telegram, Twitter, Bluesky, Mastodon, they're all full of it.
Then there's the widening of scope to big social issues that's a different matter altogether.
