Internet activism? Maybe it works by sending an e-mails too not only on webpages. I have experience to see things happen and change by the people who in mail lists when everybody is coming to talk about something. For example in kindergardens parents list.
And also come in my mind Edgar Savisaar SMS campain, when lots of people in Estonia got SMS with text:"Rise and Shine". I guess it was in the morning of voting day. About this was talked a lot in the web too.
Maybe its good if people is more active in the net. Maybe we can say, that there is internet passivism too, when people dont react on talks in forums and some awful things and accidents had happened in world.
