It's hard to get more optimal than "read a page of text" "press button for next page". Scroll wheels require some combination of
* Have to move it more to travel the same distance
* Have to fiddle with it to get exactly one page
* Have to track your position during the scroll
* Have to scroll more often than once per page
This (among numerous other near-universal UX transgressions) has gotten to the point that my first action on almost any internet article is to hit ⇧⌘R.
I've always read at the center of the page while scrolling. It's what I've noticed most everyone my age doing. Maybe it's generational, I've only been at this since windows ME.
