You know, I just quickly zoom with a double tap and nail the UX element.
We have better elements to use, but I must also say those tend to come with costs.
Right now, HN is so lean, fast and clean, I will gladly work a little to vote or do some action in return for what is otherwise one of the best "just read the discussion" presentations on mobile. It's a pleasure.
How do you vote without zooming?
Ever tried to touch "comments" on headline and accidentally clicked "hide"?
Ever tried to touch the "Hacker News" menu item and gone to "new"?
Everyone is used to these things, but they are textbook examples of bad mobile design.
