Nick Ragone, an executive at the huge PR agency Ketchum [Disclosure: and an occasional source of mine at PRWeek], has a new book out about Presidents, for some reason. And he's putting those PR skills to use for it. It's on Page Six today! He has a podcast about it! And an op-ed in PRWeek about how "real" authenticity is "essential" for corporations and politicians alike! How does Ketchum, which does everything from sell you food to lobby your politicians, teach its employees to be such paragons of authenticity in communications?
