I absolutely haven't. A source can be an article itself (as in the content), or it can be an organisation (a joirnal, a newspaper), or it can be a person. I'm saying that the source isn't the medium over which the content itself is delivered. So for example, the New York Time is a source, so is any given article and it's associated author. However, the blank paper on which it was printed isn't a source, neither is the ink it was printed on, and correspondingly a website which merely relays words is not a source, but a medium.
