"Once I have a buying customer, it's my license to sell that person anything I've got," Folio: editor Chuck Tannen said to me over lunch years ago. Recently, I did pieces on two organizations that embraced Chuck Tannen's business philosophy—American Girl and Playbill. These people blitz their audience with buying opportunities. I am continually astonished at the number of organizations with enormous databases of users who never make an offer for a paid product or service—e.g., Yahoo. I get the sense they are terrified of offending.
The most recent convert to the Chuck Tannen business model is The New York Times. I've been a reader for 60 years.
