naive

naive adj.  Untutored in the perversities of some particular
   program or system; one who still tries to do things in an intuitive
   way, rather than the right way (in really good designs these
   coincide, but most designs aren't `really good' in the
   appropriate sense).  This trait is completely unrelated to general
   maturity or competence, or even competence at any other specific
   program.  It is a sad commentary on the primitive state of
   computing that the natural opposite of this term is often claimed
   to be `experienced user' but is really more like `cynical
   user'.
