I totally understand the point about the scroll bars, I meant to say that I habitually scroll pages, without even thinking. There's no analysis, no attention to the (hard to see) scroll bar, the intuition is always to scroll. Even when it's very clear that I'm intended to be at the bottom (e.g. I can see a conventional footer layout) it's just a reflex. But yes, I agree with you it's undoubtedly common (enough). I was just pointing out the difference with "internet natives".
