I'm curious about what people would define as uniquely "American" culture, independently of any particular region.
When I look at it and average out anything unusual between different regions and eras, the picture that appears is rather bland. I mostly see 18th century European enlightenment ideals modified by Protestantism, along with a mildly localized form of British traditions from that period. And lots of modern technology and "new age" ideas that seem to be permeating the globe thrown on top of it all. The flavor seems very generic, mostly all that you can tell is that we're a Western culture with a hint of diluted British and Protestant flavor.
One thing a lot of people cite is the idea of valuing the individual, freedom, equality, and democracy, but many of those things are from as far back as Greece or the Enlightenment. You might say that "Well, they were biased because they didn't apply those ideals to women and blacks," but to be honest, America didn't either at first. So clearly, this sort of thing is not uniquely an example of American culture, but is part of our shared heritage with the Western world at large.
So far, the only uniquely American idea I've found is the idea that we're a "melting pot," and not any kind of single, homogeneous group.
So, what else would you say applies to American culture as a whole, that isn't related to a specific region, and isn't shared with Western/European/English civilization as a whole? I find myself having trouble thinking of such qualities, except perhaps for the strong Protestant influence.
It's possible that I'm too close to the problem. Maybe people from outside the U.S. could help us note a few?
