Pella, thank you. I'm going to check a few of those extensions out for their utility. It's not quite the full vision implemented, but it's a better start than improved history extensions.
This is pointless countering to an idea that is established for a reason, people reading above the fold only is largely true. But like the page says, don't take other people's word for it. But just because you shouldn't believe them that doesn't mean you should believe the opposite. If you really care about then TEST IT YOURSELF.
Caps lock applied for the importance of the point. Like many other comments are saying there is a wealth of evidence that points towards nearly 90% of users tending to only pay attention to what is above the fold, the other 10%, may read more. That 10% is important, hell they're your most engaged audience. But your design needs to only cater for the 10% and focus on the 90%.
So test your site, use a tool like http://www.crazyegg.com/ and look at scrolling heatmaps of your site. See if a page that draws users down is really working or not. Don't take somebody else's word for anything, just use studies, design cliches and common sense as a foundation for your own result based investigation into what layout serves your entire visitor-base best.
