Well, in Japan, people who obsess over the medium often go into extreme isolation. In America, they circle jerk with others, which only makes them act out more to compete with one another. Both are bad, but the latter is far more obnoxious. My theory is that it has to do with How different each country's social dynamic operates. You are expected to be very introverted in Japan when conversing with strangers, where in America it's the opposite. I know it's more nuance than that, but at face value, that's about it.
