Quite literally! The computer scientists conceive the whole internet as a layered entity (the physical layer, data link layer, network layer, transportation layer, etc.). Is it possible that we in internet research need to likewise formulate a layered conception of "medium?" In a sense, there are many who only see the hardware, not differentiating between, for example, web surfing or IMing -- it's all just "stuff on the computer." For others, finer distinctions become important. Etc. Perhaps our difficulty in determining where the "medium" exists is our confusion over which layer of the thing on which we ought to focus??? -- Mark D.
