eenu... I'm a Brit not an American so I'm very well aware of the BBC news site
My reference to New Orleans was to UK teenagers rather than the UK population as a whole since I know that Richard is relatively young and made a correlation as to the age of the Americans who might not have been aware of the tsunami.
If you read these boards regularly, you'll find that most of the Americans, who I'd say were a good cross-section of educated Americans, are pretty well informed on world events in a timely fashion. I know that several of my US friends were busy organising fundraising activities at the same time as London Underground started shaking buckets on the Tube.
Just as educated Brits tend to be reasonably well informed. However, I'd disagree that just because we have the Beeb, means that people know what's happening. Even within my office, there's a terrifying amount of ignorance about world affairs combined with an equally scary knowledge of all things celebrity or Big Brother.
