That's probably what I was trying to say Sdaji - that common usage evolves over time, but is probably "leveling out" and becoming less parochial with the increase in the ease of global communication.
Jackrabbit, I defiantly have to agree with you there!

More or less parochial? I am not sure. More or less accurate? Again, I am not sure. When everyone is unanimously agreeing on tortoises not being turtles (utterly incorrect and quite parochial) and that there is no such thing as a venomous snake (again, utterly incorrect, until the myth started to make itself correct and perhaps will become firmly correct, again, extremely parochial), and the countless other examples, it seems easier for the world to come to a consensus (regardless of whether or not it is a good or accurate or correct one) and become globally quite narrow minded. Before, different people in different areas had different views, and were arguably more willing to accept different ideas because they hadn't become so rarefied. The trend towards ridiculing and shunning different ideas seems to be as strong as ever, the desire to be sure that the conventional wisdom is accurate seems lower than ever, and the extent to which the world is unified is obviously greater than ever.
