David Seaman defines buzz as the process of getting people to discuss you, your company, or your product … for free. In his new book, “Dirty Little Secrets of Buzz,” Seaman lays out 61 tactics for creating buzz. Seaman shares some of his general secrets for creating buzz, and also provides specific tactics for tech industry firms and executives to create and keep buzz. Buzz is an age-old concept, but the emergence of dynamic social media products such as MySpace, Digg, Reddit and others provide powerful new tools to generate buzz, Seaman said.
