Say you know the people you would like to reach with your advertising message would likely be fans of a FaceBook fan page.... I'm wondering if it's possible to use Facebook Ads to show your advertisements to people who are fans of certain pages.  When I googled for “targeting fans of facebook pages” nothing relevant came up…. see here: http://www.google.com/search?hl=en&q=targeting+fans+of+facebook+pages … just info on how to get fans. I’ll email facebook and find out.
