Bill O'Reilly of the Fox News O'Reilly Factor has been introducing Dick Morris as the "purveyor" of dickmorris.com. That should offend your linguistic sensibilities — assuming you have some. The word he wants is 'proprietor.' In plain Anglo-Saxon, a proprietor is an owner. A purveyor is someone who supplies provisions such as food.
Suppose you own the Glass Crutch bar and grill. Is it that eating and drinking establishment that you provide to the public for consumption? No, you provide food and drink at that place. So you are the proprietor of the Glass Crutch, not its purveyor. It is the same with Dick Morris. He doesn't purvey his site; his site is the place where he purveys his political commentary.
Whether you have the audience of Bill O. or of Bill V. you have the responsibility to honor and protect the English language, our alma mater (nourishing mother), the enabler, if not the source, of our thoughts.
