Comment left and right (Score 1) 177
One concern I didn't see with a quick scan through the comments: How do you make universal and intuitive gestures across cultures that read left-to-right vs. right-to-left. Off the top of my head, Japanese, Chinese, Arabic, Hebrew are some right-to-left languages/cultures. A significant chunk of the planet's population. Should a left-to-right swipe go back or forward? Depends on where you grew up.
