Amazing, Is this the first real state revoltion that is happening thanks to the internet?
I've read in a few articles and it seems the internet was a major contributor to the awareness. It isn't definitive, but it makes sense since it's an easy hub to the outside world, and you can bet there's allot less propaganda floating around on the net then in Iran's media for instance.
So these young folk learned about outside happenings and stuff, and they probably became aware of outside human rights and a few other issues about their own country (inside and in international relationships), and they set out to change things. If Iran had no internet at all it would probably not have happened.
