I really enjoyed this. I would agree with other posters, saying it was more of a documentary than an article. It did get a little too broad for me, though, and I felt like the point got lost in all of the information. Also, what about the value of imagination that is so vital and enriching about reading! When I first read Extremely Loud and Incredible Close, I was shocked that you could do that with a book. Definitely enriching, and changed the experience of reading. I can see this being a huge addition to the informational experience. Edit: I had to turn off ghostery to see it. Boo.
I totally agree with you: it's like a written documentary. I think the mixture of pictures, videos, other media, and journalism is fantastically executed here. I'm still reading it, and I'm enjoying it. But I suppose I am a sucker for parallax scrolling. edit: After finishing the article, I would add: the article was very well written. The fact that I knew there would be an avalanche at some point and that I knew people would die (I wasn't sure who) created a lot of suspense. A great read, and a great experience.
