The majority of puppy-coders I've encountered (including myself) actually want to refactor rather than just add onto. They are fundamentally correct in this, but they don't grasp that 1) few companies want to acknowledge that the code base which is their greatest tangible "asset" is actually complete shit, and 2) that due to their inexperience, their refactored replacement is probably going to end up as bad as or worse than the original.
