Do you have evidence to support your claim that the true problem is moving words? I'm really not convinced. I feel especially with OS X's inertial scrolling that I can naturally keep track of where I am in an article while scrolling, it has never bothered me.
This just feels like fancy pagination. I tried partially scrolling ahead as I was reading and it disoriented me further, because the upcoming text was showing up at the top, behind where my eyes were, replacing the old text. This is confusing and not better.
