Just to be philosophical and obscure, I myself find that when I 
understand how something originated it helps me quite a bit in 
understanding how it should be used.  The 'how' is directly downstream 
from the need that was originally being satisfied and to understand 
that, an excursion into the history of the thing is apt.
