content-free

content-free adj.  [by analogy with techspeak
   `context-free'] Used of a message that adds nothing to the
   recipient's knowledge.  Though this adjective is sometimes applied
   to {flamage}, it more usually connotes derision for
   communication styles that exalt form over substance or are centered
   on concerns irrelevant to the subject ostensibly at hand.  Perhaps
   most used with reference to speeches by company presidents and
   other professional manipulators.  "Content-free?  Uh... that's
   anything printed on glossy paper."  (See also {four-color
   glossies}.)  "He gave a talk on the implications of electronic
   networks for postmodernism and the fin-de-siecle aesthetic.  It was
   content-free."
