The Atlantic today published a very good short essay on the NSA data collection issue:

There is a comparison of metaphors: the Orwellian
1984 image of constant surveillance inhibiting behavior, and the Kafkaesque
The Trial concept of an inscrutable government doing inscrutable things for hidden reasons. The author argues that the latter is far more appropriate for the current disclosures about the NSA.
Her conclusion, which I think is excellent:
...we should ease off the privacy hand-wringing and turn our attention to something much more fundamental: how we relate as citizens to our government and how much power we have in that relationship.
