That keyboard-centric design for GUIs (I clearly have never taken a design class) is what makes Reddit Enhancement Suite such an effective product, in my opinion. HN's interface is possibly just as effective in that it discourages me from taking too many actions; I can vote on basically every reddit comment I read but using a mouse to do it on HN represents such a massive barrier compared to keyboard navigation.
