From AFP:  A NATO official said Libyans have been tweeting from the rebel-held city of Misrata, Ajdabiya and Tripoli, providing information ranging from movements of troops and tank columns to shellings of towns and fleeing refugees.

"Twitter is a great source," the official said on condition of anonymity.

The official stressed that any information gleaned from the website is checked against other more reliable sources such as satellite imagery and other traditional intelligence gathering before any jets are deployed.

"On their own they don’t represent a reliable source but they do help to draw attention to emerging issues or threats that can be checked out with more sophisticated means," the official added.  (photo: Flickr/AlJazeeraEnglish)
