Cool story:
Buck, 29, a former Oakland Tribune multimedia intern, used the ubiquitous short messaging service to tap out a single word on his cellular phone: ARRESTED. The message went out to the cell phones and computers of a wide circle of friends in the United States and to the mostly leftist, anti-government bloggers in Egypt who are the subject of his graduate journalism project.
The next day, he walked out a free man with an Egyptian attorney hired by UC Berkeley at his side and the U.S. Embassy on the phone.
