I'll copy and paste what I put in the chat thread...
I was in the school web design club in high school when it happened... was on an IRC channel I frequented and we had TV's in the classroom so saw the whole thing live... kinda freaked out for friends in NY who were freaking out about not being able to get ahold of loved ones who were in that area. The US hasn't been the same since...
Spent the rest of the day listening to the intercom sitting in class doing absolutely nothing because so many parents were coming to pick up their kids non-stop.
