Colin Marshall talks to speaker, writer, blogger and entrepreneur Seth Godin. Having already built a large body of published work on the nature of ideas, how they’re conceived, how they’re spread and how they’re executed, Godin has expanded his intellectual purview with his new book Linchpin. Extending the thoughts and observations he applied to marketing in books like Purple Cow and All Marketers are Liars, his latest work examines how individual human beings, not corporations or organizations, can most fruitfully practice their art in the transforming information economy.
