I'm really digging it as well. The layout is pretty great. Whatever the CMS is, they're getting a ton of flexibility out of it. It feels like a more integrated media experience -- typography, video, photography, infographics, user comments, all pretty nicely wound.
I like the content and I like all of their aesthetic decisions but I’m always a bit overwhelmed by their layout. There’s just too much screaming for attention for my taste.
The site is obviously great despite that (and certainly also impressive).
