A lot of my friends are still saying that Facebook cannot be beaten by Google+ because people don’t change habits, because Google+ doesn’t have this or that… While I acknowledge all these fine points, I believe that unless Google+ makes huge mistakes, Facebook will have a serious contender. Facebook is the Internet behind a wall, a design that nobody ever wanted, it’s a liability for humanity. Facebook is the Microsoft of the 2010s, the “everybody in the world will have to use my products in order to communicate with each other”.
I saw the movie before and I can predict that open standards and open source will eventually win. If Hangout developers will publish the specifications needed to interoperate with Hangouts not only Skype will suffer but Facebook will too.
