I don't claim to be the smartest of software developers, but I have been around in software development for more than a decade and I have been able to grasp most of the technical articles that I read out of curiosity. But I have to admit, the past few days I have read a bunch of articles around this, including this one, which try to make it simpler to understand, but I still don't have a grasp of the basic concepts around this :) Makes me wonder, are there enough people out there, who really know how this works and how to develop for such applications.
