Possibly a good point, but alternatively, take a look at what's happened with WeChat in China. http://a16z.com/2015/08/06/wechat-china-mobile-first/ http://a16

Possibly a good point, but alternatively, take a look at what's happened with WeChat in China. http://a16z.com/2015/08/06/wechat-china-mobile-first/ http://a16z.com/2015/08/06/wechat-china-mobile-first/ It was originally a chat app, but is now a standardized authentication, payments and UI for tons of services, like booking a doctor, getting a taxi, etc. Truly seems like we're missing out by not having it.
