The three big 'design' problems I have with Hacker News (including visual design and UX) are the already mentioned horizontal text problems (some threads force a horizontal scroll even on my 1920-wide monitor, which is ridiculous), the size of up/down vote arrows (particularly on mobile/small screen devices) and the "expired or unknown link" issue. Other than those three things I think the design is fine for the site's intended purpose.
