It's very frustrating whenever this topic comes up that people see no middle ground between "the website as it is right now" and "some bloated JavaScript monstrosity". There is lots of room for improvement that would not turn it into "a bloated JavaScript monstrosity". How about bigger touch targets? Half the time when I go to vote on a comment on mobile I vote in the wrong direction and have to undo it. Same goes for using the search feature: I constantly fat-finger the drop-down search options on mobile.

Even though I usually prefer mobile websites to apps, most of the time for HN I browse using Octal instead of the website because the website is such a pain. And it wouldn't take very much to make it better, which makes it so annoying that people have knee-jerk anger to the prospect every time the subject comes up.
