Here is an interesting podcast of James Boyle on his book The Public Domain (via BoingBoing)
Professor James Boyle describes how our culture, science and economic welfare all depend on the delicate balance between those ideas that are controlled and those that are free, between intellectual property and the public domain —the realm of material that everyone is free to use and share without permission or fee
Intellectual property laws have a significant impact on many important areas of human endeavour, including scientific innovation, digital creativity, cultural access and free speech. And so Boyle argues that, just as every informed citizen needs to know at least something about the environment or civil rights, every citizen in the information age should also have an understanding of intellectual property law.
