Well Wikipedia probably wouldn't be greatly affected, YouTube would be somewhere in the middle but they already take down videos at copyright holders request so the main change is simply seeing the uploaders get done by them at source, it's really only going to majorly hit the prolific pirates who are IIRC mostly in their teens or twenties. So again lots of bitching and moaning for a while from a minority with most people just not caring and it gets struck down on appeal.Something tells me that if youtube or wikipedia got kicked off the net, a great deal of people would care.
