I am not sure what this is meant to address. The worst thing for mobile users is the teeny tiny voting buttons. I believe that votes are important and are not used enough and part of the reason is fear of accidental downvote.

The other thing that could be fixed is when someone puts a very long unbroken string in a comment without putting it in a code block. This makes the page very wide, and creates an unpleasant experience.

I have 157 karma and I can't downvote anything. How exactly do you downvote on HN? I've never seen anyone explain that (and I can't really see it in the settings either).

I believe you have to have about 500 karma to downvote comments.

For me it was: Karma = 500, the number might change over time.
