content-free
     
        1. (By analogy with "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 centred on concerns irrelevant to the
        subject ostensibly at hand.  Perhaps most used with reference
        to speeches by company presidents and other professional
        manipulators.
     
        See also {four-colour glossies}.
     
        2. Within British schools the term refers to general-purpose
        software such as a {word processor}, a {spreadsheet} or a
        program that tests spelling of words supplied by the teacher.
        This is in contrast to software designed to teach a particular
        topic, e.g. a plant growth simulation, an interactive periodic
        table or a program that tests spelling of a predetermined list
        of words.  Content-free software can be more cost-effective as
        it can be reused for many lessons throughout the syllabus.
