This is a very good primer on the issues, but some of the specific prescriptions feel a bit short-sighted. As long as you are not reading the Great Gatsby on one page, scroll length is a better indicator for article size than page numbers. With pagination you never really know how much text is waiting for you. It is too abstract. Having no text mass indicator forces the user to check with a swipe if there is more is not interaction design. And that’s very very unfriendly. There's really no guarantee with scrolling or pagination that the text density ahead will be consistent with what the user is currently observing. It could be text, images, figures, or tables. And a good pagination display (such as in iBooks) gives the user as clear an indication of where they are in the document as any scroll display. Of course, scroll bars and page numbers are just two methods for showing the focus state of a document that happen to have become standards. There's room for exploration -- perhaps even with something iA has been experimenting with in their excellent Writer iPad app, reading time: Instead of a scroll bar or pagination display, Why not just show estimated reading time remaining?
