The programming world is made up of virtual city-states that tend to keep to themselves. The device driver authors rarely share much code or ideas with the server app creators. The Windows hackers don't talk with the Mac programmers. It's as if some emperor decreed that Java City will always be at war with C-ville.
But smartphone programmers aren't the only ones interested. For many people, the smartphone is their main way for accessing the Internet. A larger and larger percentage of the mail I get comes with a little disclaimer at the bottom asking me to disregard any typos because it was written on an iPhone or an Android phone. (The BlackBerry keyboards never seemed to need this, for some reason.) If regular websites want to follow the crowd, they need to generate pages that look good on the tiny screen. They can't assume that everyone is reading the information on a desktop box. That means the Web designers are interested in many of the same techniques as the mobile app designers.
