Reason posts a useful interview with John Perry Barlow (currently vice chair of the EFF):

Every existing power relation is up for renewal with cyberspace, and it was only natural there would be an awful lot of fracas where cyberspace met the physical world. EFF has been the primary mediator on that border. We have been very successful at protecting against excessive government encroachment into the virtual world.
Copyright and intellectual property are the most important issues now. If you don?t have something that assures fair use, then you don?t have a free society. If all ideas have to be bought, then you have an intellectually regressive system that will assure you have a highly knowledgeable elite and an ignorant mass.
