I've long argued for a 'other' category as one overflow method or a homepage that is generic and subject specific pages for those that only want LLM news or Apple. I'm sure we could agree on a 10 level 'top' set with 'All' the default. That's one step closer to Reddit of course, but with the growth that HN has seen over the years you can't continue to pretend that the 'small town' measures still apply to this big city. A lot of this really is just about scale and you need to adapt to scale.
