In the past the keeping of secrets was a relatively straightforward affair. Now neither the citizen nor the state can be sure of keeping anything under wraps. That's the real significance of the spate of documents coming out of Wikileaks. The Individual revelations are mostly footling, what is entirely new is the sheer volume of them. Before the digital age it would have been impossible to smuggle this amount of material past its keepers- and, besides, it wouldn't all have been stored in one place.
The old rules, the the old ways of doing things no longer apply. As individuals we're alive to this, but the state, that hidebound behemoth, is very slow to catch on.
