DM: discretization

[Robert Nachbar]

as decision trees are much easier to induce than generalized 
classifiers, many
people automatically (and blindly) discretize their continuous 
variables prior
to the induction process.

does anyone know of general discussions of this discretizing or 
quantizing
process? how should variables that represent counts or frequencies be 
treated?
what about the situation where all but one of the cases have the same 
value for
a variable, should it be treated as continuous?
