Showing the ease with which good ideas can proliferate on the web, John Robb is launching Intelligent Defense tomorrow. ID is intended as “a series of conversations dedicated to a deeper understanding of next generation terrorism and what we can do to defend ourselves against it.” The series is a companion to Robb’s Global Guerillas blog, which itself is a research portal for books and other ventures he has in mind, and takes Doug Kaye’s increasingly popular IT Conversations model into a new topic space.
