I know I am late to see this but there is a great set of interviews on Rocketboom from the Personal Democracy Forum. Critical is the question of the internet's influence on the politics of America and further around the world. It is fine to recognize that candidates must participate online, and that conversations critical to clutch issues are going to happen online.Yet the question being asked is how do you translate that into action. Politicians and activist have been asking this for years, and now there if focus on a new medium.
Take a step back and consider the possibility of more global interaction, one focused on larger challenges. It really takes the old mantra think globally act locally and turns it on its head. Really now you can think, talk, and even act globally through the net as a communication channel. I predict the net will fundamentally change the global political landscape creating a more uniform and cohesive world population as we have more and more exposure to each other.
