Are you on an OS that hides the scrollbar? I scroll any time I hit a webpage anyway, but even if I didn't I would look over at my scrollbar and see that there is plenty of room to scroll before getting frustrated.
The designer of this page went to a lot of effort to make the blue bar at the bottom fill the entire page, without letting any of the "below the fold" content show. If you resize the window, it grows.
I don't scroll pages unless there is a visual indication that something is there. I have a nice big screen, so many pages fit fine.
Maybe I'm just an idiot who can't operate a browser properly, but I think this is a case of designer seeking elegance over usability.
