Have you noticed that google isn't very good at anything other than their search engine?

They tried G+, and it failed, they tried Google play music, and it failed. Nobody watches movies using their streaming platform. When was the last time you knew of someone using Google books instead of Amazon or any other service? Almost every successful platform they own was purchased from someone else.

I think it's a good thing to reflect on that even one of the biggest companies in the world can fail and learn from it's mistakes.
