Effects of Technology on the Events in Iran

A very interesting question that many people are watching closely "How will the internet and modern technology change the course of what happens in Iran?" More and more videos of the street marches and the violence are appearing on YouTube. One of the most famous has become the video of a young girl named "Neda" dying on the street after being shot by a sniper. This generates anger in the population, not fear. Modern communication technology is so far being used more successfully to organize than to control.

As Radley Balko writes on his blog:

Government has been murdering its own citizens for as long as we’ve had government, particularly when the people begin to pose a threat to those in power. The difference is that now, the entire world is watching. Iran’s brutality is on display for everyone to see, archived for history, in a way that we didn’t have even in Tiananmen, and haven’t had for most of human history. That, at least, is progress.

Has the methodology of political movements around the world undergone a major change?
