Ask HN: Why doesn't Hacker News improve its UI?

HN is made for a specific audience, the minimal UI supports the idea of dense information without distraction.

It’s fine. Why fixing something that isn’t broken?

How would you suggest to improve it? In my opinion, for its purpose, UI - and UX - of Hacker News are pretty much close to perfect.

It's my favourite website UI, though I don't think every site needs to be this spartan. Every time I see one of those "Hacker News for xyz" posts, they always have a nice enough site but with huge margins and padding everywhere and miss the mark.

The community can make whatever UI it wants, using the API:

I wrote one for myself:

https://hn.unlurker.com

Or there are various ways to restyle the main site with a browser script.

What do you believe needs improving and why?

I'd like to see the gray body text become a little blacker, but that's about it.

The only requirement from me is to add favourite button to the main page.

Making that observation is an rite of passage on HN.
