This comment is a personal anecdote. People respond to text in different ways. But they respond to visual motion more predictably. That has been my observation over the course of a year while experimenting with writing an electronic book. The book began as an Android app; and when shown to an audience the general response was one of disinterest. They'd read a few lines and stop, then comment on the photos. Maybe this was because the book was bad, but to me it seemed people did not want to read a lot of text. Perhaps the content was boring? I don't know. In an attempt to promote the work, I generated an auto-scrolling screencast of the book --- which resulted in (slightly) more interest. Consequently I've shifted to converting the book from an Android app to an autoscrolling mp4. It's a work in progress, and I'm prone to unrealistic optimism, but maybe this is a step toward a format for future written works [0].
