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.
