Unique and Indispensable

Was just reading an article in the Inman News about the LA Times axing its real estate section (http://www.inman.com/news/2008/08/4/los-angeles-times-axes-real-estate-section).  That is a move that is probably long overdue for most newspapers according to everything I have been reading and experiencing the last few years.  But what intrigued me most about the story was the editor talking about wanting to provide something that is unique and indispensable.  What a great concept!!!…how many companies actually keep their arms around the idea of providing a product or service that is unique and indispensable?  What companies would you miss if they suddenly disappeared?
