My personal experience: borders around each article with so much padding makes it harder for me to scan. My eyes have to travel more to consume the same amount of information as the standard view and (at least on mobile) I have to use my finger much more to gather the same amount of info. On current HN, I can read about three or four entries before I have to move my eye. On this redesign I can really only get one in a glance because of all the visual design elements intentionally breaking up my attention. Not to mention centering the score by highlighting it with a giant orange square. I can see how you’ve sought to incorporate modern web design principles, but in doing so you’ve made it less useful for quick readers like me.
