Egypt's internet activists have played a key role in the pro-democracy protests from the outset, but they tell the BBC that the online campaigning is evolving to suit their real-life activism in Tahrir Square.

We’re almost two weeks into the revolution in Egypt and the American media keeps asking the question that my extended family asks during all world events: Is it good for Israel? Ask a Jewish question, get a Jewish answer, by which I mean, another question: What’s good for Israel?

As the tsunami of popular revolt continues eastward from Tunisia towards the Arab heartland, engulfing Egypt and threatening the autocracies of Jordan and Yemen, it has inevitably drawn comparison with a similar wave two decades ago.

Hundreds of thousands of Egyptians, many wearing bandages from from days of street fighting, turned out in Cairo’s Tahrir Square on Friday for what they are calling the ‘Day of Departure’, a nationwide call for the immediate removal and prosecution of Hosni Mubarak who has ruled the country for 30 years.

The age of the image is upon us and the clock cannot be turned back. And yet the Mubarak regime is in denial. It started with muffling the voice of al-Jazeera. I was fortunate to be in Cairo during the first two days of the current uprising.

The age of the image is upon us and the clock cannot be turned back. And yet the Mubarak regime is in denial. It started with muffling the voice of al-Jazeera. I was fortunate to be in Cairo during the first two days of the current uprising. On January 25 and 26, when the roads around me were starting to be blocked, when sirens and loud speakers could be heard in the areas surrounding Tahrir Square, and when both the police and protesters were mobilizing in larger numbers than ever before, I was struck by the inattention that al-Jazeera was giving the protest.

Gil Scott-Heron once sang that the revolution will not be televised. The Tunisian revolution, and the continuing Egyptian uprising, would seem to refute the great man’s chorus.

As Arab regimes struggle with demonstrations fueled by Twitter and Al Jazeera, and U.S. diplomats try to understand the impact of WikiLeaks, it is clear that this global information age will require a more sophisticated understanding of how power works in world politics.
