I missed most of the content on this ... page ? Exhibit ? Installation ? whatever it's called, because it told me to scroll, I did, and I scrolled through a bunch of what looks like empty space and arrived at the end ("and that's how search works"). The user is apparently supposed to stop and watch some animation at certain places, but it's not clear where to stop scrolling.

Perfect example, near the top there's some text about "It's made up of over[........] 30 TRILLION[.........] INDIVIDUAL PAGES[........] and it's constantly growing." But there's nothing to indicate that I should stop somewhere and wait for some more text to show up.

Maybe they should limit how far down you can scroll by setting the height of some element, and only increase it when the animation is finished.

Edit: the key problem here isn't the "scrolling makes things happen" gimmick that's popular lately. the problem is that it starts certain animations or fade-ins some time after I've already skipped past an apparently blank space.
