You just have to scroll harder. Seriously. Every time it got stuck for me I just tried scrolling faster and after a few swipes it would move on.

However, navigating the page is confusing as hell, I stumbled through it by using the little arrows on my scrollbar. Everything else would catapult me to seemingly random positions on the page. Seems to me they hijacked scrolling to make "one line down" "one section down".

Not going to lie, after fighting with the scrolling, I closed the page and came here to look for an explanation what this is all about - not going to click any links there.
