@melroy @jon I wonder how much damage smartphones, now being most people's main interface to the world, have done to discourse and reading. I've heard that *most* people don't own computers. And I know that trying to read any documents or longform articles on a phone is cumbersome and irritating. If someone sends me a link, I email it to myself and read on a real screen. Most people don't have real screens... so they only read tweet length content. Have smartphones destroyed attention spans?
