It's posted for all the world to see, but if I work in Gov't, then I must adhere to the security limitations so the only people who won't read it are in Gov't.
Update from the drive home:
And then I thought about it a bit. Those with clearance randomly undergo security screenings and occasionally polygraph testing. One question usually deals with "Have you seen, read or otherwise had knowledge of classified documents for which you did not have the proper security clearances?" If I had seen something on Wikileaks, the honest answer would have to be "Yes." That would lead to a whole lot of unpleasantness.
This advice might just save a few jobs.
