This seems like an “Ask dang”, and may be better served by an email to hn@ycombinator.com.

I personally would rather see other usability improvements for touch devices on the size and positioning of the voting buttons and better spacing between the various links to a user’s profile, date and time of submission and others (like hide, past, favorite, discuss, etc.). HN has quite an unsatisfactory UX for touch devices (and arguably even on a mouse pointer interface). I also see these as accessibility issues.
