Crap code is written by noobs and newbies. Not from the tools. There may be some need to fix here and there. But that are minor flaws that can be fixed very quick with running w3c validation and clean the flaws up. Which is ways faster than spending weeks to handcode the stuff.

The point is, most of the times a working code is good enough. No need for extra polishing just to catch the hand coders eyes. And Dreamweaver and Kompozer produces working code.
