Social networks, the personalized Internet, and always-on mobile connectivity are transforming -- and expanding -- social life. In the new social operating system of "networked individualism," anyone with an Internet connection and a bit of digital literacy can create online content that has the potential to reach a wide audience. This BIT explores how the boundaries between producers and consumers are becoming blurred, with noncredentialed amateurs participating in many of the arenas that were once limited to recognized and sanctioned experts.Purchasers of this MIT Press BIT will also receive a discount code (good on the MIT Press website only) for 40% off the price of the book Networked, from which this BIT is excerpted.
