I have to wonder if the staggered deployment of the leak has anything to do with savvy, or more with his own need to digest what he's got as he works through it and reports as he goes.
Either way, the story has more legs than past revelations, so I'm happy for that, and I certainly would love for it to be the case that there is a degree of effective calculation behind the deployment of the info with the goal of keeping the conversation alive and neutering critics. Goodness knows that this story needs all the help it can get. It's up against not only the resources of some of the most powerful governments on the planet, but also the lacking attention spans of their populations combined with relatively disinterested media.
I'm heartened that the noise level has remained so high since the first Guardian article (in this latest series).
