This is definitely true, and it's a limitation of the Web that's important to remember. Nobody wants to read long textbook sections - or even a novel - on a computer screen. CBT designers long ago realized that they would quickly lose their audience if they forced students to wade through page after page of text. On the Web this effect seems to be even more pronounced. People tend to be looking for quick information nuggets; they don't usually read for depth.
