I can't believe the director of the NSA (also an Army General) showed up in bluejeans and a t-shirt. I'm sure it was a PR move, but I still can't believe it.
probably a recruitment drive for the interception center they are building. That 260 million people statement is pretty stupid, considering facebook is in and around 4 times that. How stupid does he think people are?

Not just for the interception center, but they are recruiting the best pen testers and vulnerability writers since they run the main offensive arm for the US Government.
Stuxnet was written at the NSA, the other worms were almost certainly were partially written there. The MD5 signature collision attack was almost certainly developed there. You could imagine that they now have dozens, if not hundreds of developers working on finding 0day and integrating new exploits into their attack arsenal of worms.
I suddenly have a handful of friends form the old underground who went from working openly in the security industry on papers, audits etc. to no longer talking about who they work for.
I can only put two and two together and conclude that the NSA has been on a hiring binge the past few years and are hiring all the best security guys (exploit developers, more specifically).
