Cool concept aside, the scrolling behavior on this site is not one I would copy.
Thanks! Would you go for a continuous scroll rather than step by step presentation?
Yeah, continuous scroll with fade in is the standard. Odd scrolling behaviour like this only frustrates me when trying to scroll and it snaps back to the original position. If you're going for a step-by-step flow, it should use tabs or something similar, instead of modifying standard scroll behaviour, just my $.02
