Sorry I know I already quoted and answered this but what you said made me think of something.
There's an idea that Americans are 'inward-looking' and uninterested in the rest of the world. I don't think that's fair. My experience in visiting the US and communicating with many Americans online indicates that there are many, many Americans who absolutely do take an interest in the non-US world. Obviously not as much as they do their own country, but that's true of all of us for obvious reasons.
I've also had some amusing experiences with Americans who don't know much about Britain ('Oh I know Wales, it's in England!' and 'Wales? That's north of England right?' and 'So does the UK have a president or what?') but those people were well-meaning, expressing an interest and I'm sure plenty of Brits make stupid mistakes about America when talking to you guys!
Now obviously the Scottish referendum stuff isn't big important news to anyone outside the UK yet. Maybe when it gets closer other countries will notice. So the fact that you haven't heard of it yet isn't so surprising.
But I am astounded that NBC didn't even bother to look up Tim Berners-Lee. His invention changed the world and he's a professor at MIT!
