I wonder if a criterion based on "did it get you monetary value" is useful to make these judgements. If you take a css color line from a page, could you have chosen another color to equal effect or chosen this line from somewhere else (i.e. is it common knowledge)? Is the color so unique that it would take someone a lot of money to have figured out that that was the "right" color? If you take some code and then rewrite a substantial part of it, did it save you time? (= Money) ... that you would've spent had you not had that code to start with?
