> zoom in to full width Narrow column layout are awesome: You can zoom in to full width, resulting in big fonts for your screen. Most website's fonts are too small by default to be read on an iPad. It gets worse when I'm on a subway or reading while walking home (90% of my HN reading time): Font to small, can't zoom, = leave the website. So rule #8: Let people use the pinch-to-zoom on your mobile website (Ironically, the OP itself has pinch-to-zoom disabled). Which leads me to a more important point: Why do "responsive" js libraries sometimes disable pinch-to-zoom?
