Don't agree. FB growing fast yes, but Google's revenue still dwarfs FB. FB is walled garden, in the long run, there always fail, the open web platform will prevail. I will never use FB as my window into the world of events and news. Microsoft is still has some power, they have embraced the open web and are even collaborating with Google, Eg Typescript Angular2, to counter the FB threat, I'm sure also that Apple and Samsung will be hostile to FB dominence. Also new recent web standards, esp web components, will finally enable the web to be an application platform.
