It is undoubtedly possible, in some circumstances, to sell icy snack concoctions outdoors in the dead of winter, fruitcake to those who loathe it, and tickets to the opera to those who prefer to “rock on!” Those may not, however, be the most prudent marketing moves. Omnipresent social media giant Facebook now offers a new mechanism, called Open Graph, with detailed historical records of peoples’ interests, hobbies and relationships. It can be used powerfully to target your advertising to those who really would be interested in it. (Sure I can’t interest you in some fruitcake?).
