second-system effect n. sometimes, more euphoniously, `second-system
   syndrome' when one is designing the successor to a relatively small,
   elegant, and successful system, there is a tendency to become grandiose
   in one's success and design an elephantine feature-laden monstrosity.
   the term was first used by fred brooks in his classic "the mythical
   man-month: essays on software engineering" addison-wesley, 1975; isbn
   0-201-00650-2. it described the jump from a set of nice, simple
   operating systems on the ibm 70xx series to os/360 on the 360 series. a
   similar effect can also happen in an evolving system; see brooks's
   law, creeping elegance, creeping featurism. see also multics,
   os/2, x, software bloat.

   this version of the jargon lexicon has been described with altogether
   too much truth for comfort as an example of second-system effect run
   amok on jargon-1....
