It is interesting to see how the question itself is perceived. Welcomesite seems to take it as bashing but I assure you it was not meant that way, and it is a legitimate concern I have had. Contrary to the idea that is is putting others down, it is a humbling thought to me to realize that whatever I am doing, I am standing on the shoulders of giants as it were. Paints and brushes don't count, neither do microprocessors or cathode ray tubes.
