I know that many do not believe that clean code is all that important.  I do though.  An example is a shopping cart that I had to fix last week.  It was written by an off-shore firm (and there’s nothing wrong with that in and of itself).  The problemwas that the top include file (a server side include) had so much junk in it that the cart would not work in Firefox at all.  As soon as the junk was cleaned out and what was left properly code the cart functioned properly.
