I sure do.

So you don't like it because .... you don't know what it means?
Why would you want to "know what it means"?

A scrollbar is nothing more than a bunch of pixels that give you some rough
idea of where you are (and how much of the rest there is left to see), along
with some way to move with the use of a mouse.

I believe that confining oneself strictly to some analogy to the physical
world is just plain dumb.  What's the benefit, concretely?  No user has ever
complained that she doesn't understand how Emacs scrollbars work just
because they "slide off the end".  When the thumb slides off the end, all
users know immediately that it "has slid off the end": they understand it
completely intuitively.  Only GUI-nitpickers get annoyed that it doesn't
conform to some model.
