Flexibility...

...is the key to airpower.

This story is from a couple weeks ago, but I just saw the quote in the final paragraph for the first time:

Air Force Blocks Access to Blogs

Nearly three years after the Army took notice of Soldier blogs and began insisting the writers register with their chain of command, the Air Force is going in a different direction altogether: restricting which blogs its airmen may read.

But while the Army -- which now has regs requiring security reviews of blogs before publishing -- acted to keep sensitive information from getting out, the Air Force’s move appears driven by a desire to choose which news sources are legitimate.

As a result the Air Force Network Operations Center at Barksdale Air Force Base, La. - the so-called "Cyber Command" - has slapped a ban on all sites with "blog" in their URLs, the magazine Wired is reporting.

The magazine quotes a command official as saying Airmen may still access information sources outside official Air Force outlets, but only "primary, official-use sources."

"Basically," said Maj. Henry Schott of the command’s plans and requirements section, "if it’s a place like The New York Times, an established, reputable media outlet, then it’s fairly cut and dry that that’s a good source, an authorized source."
