"Jared, I realized after I hit 'Send' that I was danger of implying that
'design = making things pretty' or something similar, but the deed was done.
 Design and Usability can be treated as:
1.  Two ends of a continuum/spectrum
2.  Two sides a coin
3.  Two intersecting circles in a Venn diagram
4.  <insert your favorite metaphor here>"

I have always thought this was the wrong way to view the difference between
usability and design. It makes it seem as if they are part of the same
process. My way of thinking about them -- which at least makes it clear for
me -- is that usability testing *measures* the success of design. Once you
get your measurement of success or failure, then you *design* a new solution
-- two different processes.
