On January 18, Asmaa Mahfouz posted the video below on her Facebook page urging men and women to take to the streets and demand that Hosni Mubarak step down after 30 years of autocratic single-party rule in Egypt. Many people reportedly followed her lead, posting their own pictures holding a sign similar to Mahfouz's, expressing their intention to take part in a day of protest on Tuesday, January 25. The Mubarak regime has since shut down the Internet.
According to the New York Times, our rabble rouser celebrated her 26th birthday among tens of thousands of Egyptians yesterday. Mahfouz is a member of the April 6 Youth Movement made up of young people who have successfully used social media to mobilize Egyptians against their country's leader. Her group has been credited with playing a major role in organizing this mass demonstration.
I think you'll find her courage inspiring, especially since she chose to show her face and disclose her identity.
