Burson-Marsteller press release: “The results of the fifth annual 2005 PRWeek/Burson-Marsteller CEO Survey reveal that while blogs are increasingly making headlines, only seven percent of CEOs are actually blogging and many are skeptical about starting a blog themselves. Despite the low numbers, 59 percent of CEOs said blogs are useful for internal communications, and 47 percent said blogs are effective for external audiences.”
