pieriansipist

n. An intellectual dilettante, one who only "sips from the Pierian spring"

The consensus was that it was derived from the Pierian Spring, and meant
someone who only dabbled in learning. That would make a pieriansipist
someone who has sipped from the Pierian Spring and therefore slightly inspired
by the Muses.

A pieriansipist can often be found in the world of the Web, wherein it is easy to
read a little about a lot, and thus know a dangerously small amount about a
great number of different things.
