It’s my thesis that people will scroll almost infinitely. Just give them high-quality stuff. At Microsoft they did research and found most people won’t click on the “next” button. But, they will scroll. You’ll notice that the search engine at live.com doesn’t ever end. If I remember the research right they are finding that people look at something like five times more information if it just keeps scrolling than if they have to click next.
There goes one of my arguments…
