Hundreds of men, their arrival coordinated by uniformed security agents, attacked the anti-government protesters with knives and sticks, prompting the majority to flee....

It is already spreading, or more precisely it's already there. My only worry is Internet control. I've been fighting here in Tunisia against censorship because I knew that infrastructure is the key for change. In some parts of the Arab world Internet access is maybe still not enough developed to be a lever for change. So maybe it's just not the right time, and maybe it's more effective to focus on having internet infrastructure ready and free right now.

While we begin with an analysis of the challenge on the Day After for the Egyptians, "Yesterday Celebration, Today Hard Work", we are already drawn to Algeria where the opposition is attempting to march in Algiers. The protests are challenging the regime of President Abdelaziz Bouteflika, which has ruled with a State of Emergency since 1992, complaining about mismanagement, corruption, and a "police state".
There is a heavy security presence, with 30,000 police brought across the country to the capital. One blogger, observing the fleet of police vans and the riot gear, says, "It's scary. It's unbelievable." At the same time, he notes, "The fall of Mubarak came at the perfect time."
Even as the world was being changed in Egypt, there were protests elsewhere. In Yemen, thousands continued the pressure on President Ali Abdullah Saleh. A Facebook video indicates that the challenge lasted into the night. In Jordan, where King Abdullah has been pushed to replace the Government, "hundreds" demonstrated in Amman.
Organisers are hoping to get demonstrators on the streets in Bahrain on the 14th and Morocco on the 20th.
And dare we note --- given we have covered the situation every day since 13 June 2009 --- that against all the weight of regime oppression, the Green Wave is hoping to appear again in Iran on Monday?
