Famous author (he’s sold more than 100 million books) Paulo Coelho just arrived here at Davos and I turned on my Nokia and broadcast it live from the World Economic Forum. Mike Arrington introduced him to me and he gave some good advice for new authors. More to come from Davos over the next four days. Why did Mike’s mood need improving? Well, yesterday in Germany someone came up to him and spit in his face and he wrote on TechCrunch that he’s taking some time off of blogging.
