"Leave, leave, Mubarak." Redditor snaps an inspiring photo in Tahrir Square, Cairo, at 11pm. Hello, little brother.

People -- not tweets -- revolt, but social media help us witness the revolution. According to the redditor who posted this photo to /r/worldnews, the image is now being carried on BBC, Al-Jazeera, and other main stream media outlets.

This is just the kind of thing I was talking about on Bloomberg yesterday.

My thoughts are with the people of Egypt, longing to be free.
