Student's Twitter messages alerted world to his arrest in Egypt
http://www.mercurynews.com/ci_8934411?IADID=Search-www.mercurynews.com-www.mercurynews.com Pretty amazing 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."Replies
Twitter AND cell phones, that is.
I think I have to go lie down now.

Wow. Twitter actually accomplished something.
