Post on Lui's hypertext

I can understand why it would be hard for Lui to find information on the reading patterns on electronic media because it's so hard to assess a person's change. While Lui was discussing how people change their reading patterns and the process scientists are using to study the change, I was looking at myself read. Impossible, I know, but I was slowing down and speeding up the when I was reading. I was watching which words I skipped over or what things grabbed my attention. The study is definitely warranted from my stand point. However, I wonder what use the information is being put to, and is their future change in reading habits that will occur even after these studies?
