Yes, I do, and I can give you an answer for each example you gave. I'll start with the final example, because it's the one I remember best. Quorum is not written by journalists, it does not gather information. Conrad Black is not a journalist either, unless, at some point in time, he found out the identity of the source of one of his journalists. Only in such circumstances would he be considered a journalist. The Yellow Pages are not written by journalists.
