I have experienced the same problem myself. An even simpler (partial) fix would be to just move the buttons further away from each other. They are so close at the moment that hitting the right one on a touch device is basically pure luck. You could also use JS to add an "are you sure?" popup upon hitting downvote. OTOH HN actually has a fair number of usability issues, though it doesn't seem like there is much interest in fixing them (I'm sure PG has plenty of other things to do). I think this might be partly because this board is written in some form of LISP so less people will be comfortable tweaking the source. Would it be heresy to suggest a re-implementation in something like rails, or gasp even PHP?
