Twitter for Freedom.

“[James Karl] Buck, a journalism grad student, was arrested in Egypt last week, and his only communication to the outside world was through his cellphone, which he used to post a message on the micro-blogging site [Twitter]. ‘Arrested,’ he typed into his phone, a message that broadcast via the Web to his friends in the United States and bloggers in Egypt.... His friends contacted the U.S. Embassy and his school, the University of California at Berkeley, which sent a lawyer to get him out of jail.”

A good use case to add to the repertoire of texting and activism. It’s like your own personal urgent action network. Thank you, Blaine!
