In separate reviews published Thursday, CNBC’s Gloria McDonough-Taub and TIME’s Andrea Sachs praised “Satisfied Customers Tell Three Friends, Angry Customers Tell 3,000” (Doubleday), the new book from Nielsen Online’s Executive Vice President of Digital Strategic Services, Pete Blackshaw.   

Sachs concluded that the book, which offers guidance for marketing to Web-empowered consumers, “deserves a spot on the desk of every executive who worries about his company’s reputational risk.”

In her “Bullish on Books” blog, McDonough-Taub echoed that advice: ”‘Satisfied Customers’ is a great guide for business leaders and marketing officers who want to build a trusting, authentic and lasting relationship with today’s vocal consumer,” she wrote.
