If nothing else, this is a great example of how perception is everything. The only reason our government is as it is is because most people feel apathetic or feel like they are unable to do anything to change it. The same is true of Iran, except now they are seeing countries in similar situations where people are uprising against the corrupt dictatorships. Nothing in Iran has changed other than the peoples perceptions of their power.

Also, there's no doubt in my mind that the internet will continue to be a tool of revolution. Wikileaks/4chan/etc have shown the power of the internet pretty well IMO. But be prepared to start seeing backlash from the people in power attempting to stop it. The powers of the world are not blind, I'm certain they know about this already, and I'm also certain that they are terrified by it.
