Kleiner examines capitalism and the possibilities for cooperativism/communism in the digital age, especially in regards to peer production and licensing. Useful distinctions drawn around production, materials vs. digital, and digital labor. Growing dated in some areas, but on the whole still very relevant to today. Kleiner proposes a new licensing model to promote Peer Production / Venture Communism and presents meaningful and substantive arguments against both copyright and standard copyleft licensing models (like GPL, Creative Commons, etc.) from a leftist perspective.
