@Jeremy, that's what I thought of too

Maybe I'm a bit more sensitive about this issue then some others, maybe it's because 9/11 is my birthday, maybe it's because I spent my birthday that year trying to find my father who drove a car professionally in NYC at the time of the incident. My father made it home safe, thousands of other kids age 14 or younger lost one or both of their parents that day, can you relate now? Imagine for one moment that at that age (14) a plane crashed into your parents office and they were burned alive slowly or were forced to jump out of a window so high above the ground that there was 0% chance of survival, or that part of the building fell on them as they were trying to rescue survivors from the lower floors, or that they suffocated in the street from the enormous clouds of dust that were inescapable. No really imagine it, now imagine that you are watching it happen on the news for some small chance of hope that they might have made it out. Now is it worth talking about? That's not to mention the poor people that died on the planes, most of them going on vacation and instead get crashed into the world trade center while their families watch it happen on national tv.
This is why the world cared, it's the same reason we cared about tsunami's, earthquakes, car bombings, trapped miners, and many many other disasters, because to not care would display a total lack of empathy for anyone and make you a douche bag.
They thought it was something worth talking about for that reason, people are still people no matter where they live, no matter how far away, and a tragic loss of thousands of lives touches anyone with a soul anywhere around the world.
