Let see how we could improve this. Browser Extension/Plugin with a site whitelist. When you browse to the site and there is significant content below the fold you get a tiny popup informing you that scrolling will start in X seconds unless you hit cancel (or perhaps just move the mouse). All you would have to do is browse to the site (I imagine, ReadItLater, Readability etc. to be typical sites people would use this extension with). Just a though.
