OpenP2P.com: Piracy is Progressive Taxation, and Other Thoughts on the Evolution of Online Distribution
An extremely interesting article by Tim O'Reilly. He has some excellent ideas about P2P, or peer to peer for those of you not in the know, and why people might pay for filesharing services. He also has some excellent ways of looking at P2P filesharing, for example, as the title says: piracy as progressive taxation. Excellent read and worth the length.
