    Remember what Billy Shakespeare said about roses...

When you communicate using words, the words you choose determine
what message you convey.

People can find out about roses by looking at them, smelling them, and
pricking themselves with thorns.  But a social activity such as the
Free Software movement consists primarily of the thoughts people think
while doing it.  The only way to convey understanding about the Free
Software movement is with words.  So it makes a big difference what
words we use.
