If we are serious about political and social change we have to embrace all the technologies available to us. Especially in a country like Iran where the state has a monopoly on education, media and most cultural events in the public sphere. Creative use of new media and technology was instrumental in getting rid of repressive regimes in Indonedia and Serbia (have a look at these interesting but dry articles on the spread of internet and its role in the revolutions of Indonesia and Serbia Serbia ), but even in the west the world is changing fundamentally: in a time that newspapers suffer from poor sales and ad-revenues one important reason for Obama's victory was his supporter's embrace of new media like blogs and Youtube.
One man who understands all this (and more, I'm struggling to catch up with him) is Arash, a Persian blogger in Canada. In his great blog he posts about current events in Iran, and especially things that happen in Iranian cyberspace. For instance, check out his recent post on the creation of the new digital police in Iran: http://kamangir.net/2008/12/18/new-digital-police-to-establish-in-iran/
So there you have it. If there's a new revolution on the way it will present itself in small messages delivered to your computer with hip music and slick animation.
