It took me about five minutes to figure out what was the point of this website. I'm on a 13in Macbook Pro and didn't realize you could scroll down to see the buttons. Does it bother anyone else when people design websites for tall screens that most people on laptops just don't have?
"The fold" is important in many places; games and other web applications should indeed be visible from the start. It's true, we have now scroll bars and scroll wheels and scroll areas on our touchpads, so it's not as important as it was in press, but it surely does need to be considered. It always upsets me to see news sites which have too much crap at the top of the screen getting between me and the thing I came there to read.
In this case, you are simply wrong about the application of "the fold", though. The point is, this is a simple web page containing a link and an application. The application is large enough that it cannot be reasonably guessed to live in the top 400-500 pixels of the screen. So there should have been a visual cue to distinguish the application, perhaps a box around it, so that people who have not yet seen the buttons at the bottom will scroll down and see them. Right now you have no idea where the application resides, and that is the complaint.
On Mac OS X Lion, in Safari, scroll bars are hidden by default. They are only shown when you start to scroll, using either the arrow keys or the two-finger-drag gesture. So if the page looks complete and you don't try to scroll because of that, you have no indication that there is more to the page.
Edit: the scroll bar is also shown briefly when the page finishes loading.
WorldWideWeb had scroll bars. Since day one of the web, browsers have been expected to gracefully handle documents with too much content to easily render on one screen. It's not reasonable for every author worldwide to have to simultaneously munge all their documents just because one browser maintainer woke up thinking it would look cooler for you not to know if there's more to read.
1280x800... i didnt have safari maximized but it was a pretty big window already. Even after maximizing it the follow button was still below the fold, when clearly this entire website was designed to be viewed in one window.
I don't see the buttons on Chrome before scrolling on my 13" MBP, but since I'm stubbornly sticking to 10.6 I did get a nice big scrollbar to let me know to scroll down. :)
