I've had a similar gripe with scrolling, although I encountered with text editors instead of browsers. Having used Sublime Text for a while (which does what the article suggests and shows you as much white space as is needed to keep the display consistent), it is really jarring using many of the other editors which refuse to do this, especially as I often tend to write new code at the bottom of the page.
Being forced to consistently look at the bottom of my screen instead of the top or the middle is pretty annoying, maybe a change in browsers could trigger a change in text editors as well!
