I received an email from Ken Hollis, who told me he had been fired from NASA for posting publicly-available materials not to a blog, but to a Usenet group.

In 1998 testimony submitted at the request of The Subcommittee on Space and Aeronautics of the House Science Committee, Keith Cowing, the editor of NASA Watch, said:

When NASA contractor employees speak out, the fate is far worse. When Jim Oberg, Ken Hollis, and Tom Hancock (a.k.a. “BitFlip”) exercised their constitutional right to free speech, and discussed NASA without PAO permission, they soon found their jobs in jeopardy such that they had to leave their jobs. These individuals spoke of nothing proprietary and often spoke and wrote things that made NASA look good.

New communications technologies, it seems, always put some kinds of people on the defensive.
