In order to get that level of display control, they're doing some insane things under the hood with the HTML. It's a tag fiesta in there (understandably -- there's no other way to do it), and complex HTML can put some real demands on the processor -- but nothing compared to the same content in Flash.

In Safari scrolling that document is very smooth. So much better than the Flash Scribd. Kudos.

Yeah. Even if scrolling is laggy, it's arguably better than having to click "next" for every page.

There is a lot going on under the hood, and we have put substantial work into optimization for things like scrolling through content. We know we can still do better, though, so expect to see things even more performant in the coming weeks!
