http://www.opendemocracy.net/debates/article-8-101-1459.jsp Siva Vaidhyanathan, author of the forthcoming The Anarchist in the Library and a true scholar of the internet age, presents a compelling, five-part panorama of the implications of electronic peer-to-peer networks for culture, science, security, and globalisation.

Bill Thompson of openDemocracy responds to Siva in a sparkling exchange of powerful, lucid intelligence.
