Author/journalist Bill Wasik discusses the ephemeral qualities of culture creation in the current era of blogs, social networks, and nanostories. He was invited to NextSpace to review his new book "And Then There's This." He answers such questions as "What is your favorite FlashMob story," and thinks us through ideas like "spreadable" vs "viral" culture.

Bill is a senior editor at Harper's magazine and the inventor of the "flash mob."
