It helps that British geeks love James Bond and Alan Turing, and at GCHQ they get to play at being both - although you'd have to hope some of them have wondered if this time round they might not be the unequivocal good guys.

Also, if you get a reputation for hiring the brightest and best, you also get people who've spent so long being told they're the brightest and best that they may have little concern for whatever lesser beings get spied on, shamed, discredited, disenfranchised during their fun intellectual challenges.

Right, I'm on a list somewhere now! Hi echelon.
