Much has been said/written already about the Facebook community and where users are. There is a long term trend that early adopters of Facebook (read Western world) are using Facebook less (though using their OAuth identification more). Facebook is growing in the rest of the world (read Asia - WhatsApp has a billion non-US users). The main means of internet access (almost exclusively) for these users (the next billion Facebookers) are feature phones and smart phones. Through this context, it is quite intuitive why they are making the decisions they are.
