Off topic, but then again maybe not. A great read about Over The Top vs Mobile Carriers/Operators:

But most of this will come to nothing and the OTT guys will triumph until carriers realize that having software DNA is a necessary condition for innovating in the world of digital services that many carriers believe they occupy. This too, is an inescapable fact.

Paul Golding nailed it. I have worked with Mobile Operators for years and I always regret never seeing an operator building a software stack aimed at creating unique, differentiated services for their customers. That DNA is almost extinct in mobile carriers now.
