Excellent posting here: Link to John Battelle’s Searchblog: Google as Ad OS? Sure, If You’re A Programmer . I like it, not only because I work for Microsoft (I’m Trade Marketing Manager for Microsoft Digital advertising solutions in Belgium). I like it and believe it because of what marketing is all about. More and more it’s about emotions and the link the consumer wants to make with a brand (or not) and that’s where this posting has it right.
