Not much to be honest. I always laugh at this america-centric attitude about 'the world'- most of 'us' honestly don't think about the States that often. It doesn't come up in daily conversation.
Sorry to hijack.
Not a hijack, just option #3
No, it's more when I answer their question with the word "Chicago". That's when they say "Al Capone" and mimic the Tommy Gun. It has nothing to do at all with how the rest of the world occupies their time and attention. Stimulus and response.
Very few non-Americans hear the word "Chicago" and blurt out "Borat Obama" (yakshe mahsh)
Neither do we who live in the Big Stinky Onion (google it).
The America-centric perspective squelched, the thusly inconsequential individual who is referred to by most as "the leader of the free world" is a pure distillation of the School of Chicago Politic, although he likely prefers his pizza as a "Hawaiian" ( pineapple and ham ), possibly tofu.
I don't perceive myself as jingoistic in regards to the USA's impact on world events, but even the BBC news seems to find some evidence of the USA tail wagging the dog on a daily basis. After all, we might not have invented pizza, but we did make it the worldwide health threat that it has truly become. That and the 32 ounce Coke. (946.352 ml, but we want it with ice) The US would dominate the world if we had adopted the metric system for weights and measures. We did at least create the use of Decimal Currency and that seems to have worked out well for us in that arena.
The minute someone somewhere will not take a $100 USD note from me I will know that the world doesn't see it from Murican perspective. Now that everybody has printing presses, they don't have to put up with the long standard world map with the US in the middle style. Yes, the world and ones perceived location within it does alter dramatically depending on your longitude.
That's why I subscribe to British (and German, and French) dive magazines. A different worldly perspective. Besides, sometimes they have real nekkid wimmen in them, so there's that!
I have had French Pizza in Chamonix. I can also tell you that whatever it was that I ate in Germany and England was their perception of what Pizza should be, bless their pointy little heads. Better that than mixed grille or germknodle. But, I have ventured down Path #3 far too long here....
Trip Advisor, again... My main confirmation is with the TA Forums. It really paints a picture of the low level of SCUBA awareness by questioners and 99.3% of those who answer. SNUBA, snorkeling, where can I rent gear, pretty low level kind I'd stuff compared to SB queries. Luckily there are any number of salesmen who post responses. These commercial answerers seem to have greater longevity, posting for many months, versus the flash-in-the-pan SB "professionals" who seem to come and go. I think the comments in this thread so far are confirming my perception.
