I remember going to a user testing session, and marvelling at people (and it was a clear majority of the 10 or so people we tested with) scrolling the long web page by moving their mouse pointer over to the scroll bar (and it was a huge monitor, so that was a long way), clicking and dragging up and down. I had just gotten so used to, well, every other way of scrolling (mousewheel, trackpad, arrow keys, page up/down...) that I'd almost forgotten that scroll bar existed. I guess there's not much we can do about that: scrollbars are at the mercy of OS and browser vendors really.
