I think this is actually a pretty deep question, philosophically. When you photograph a landscape, are you trying to produce an image of a "pristine" landscape, uncontaminated by the icky business of humanity?---or trying to show something about the interaction of people and places?---or telling a fundamentally human story in which the landscape is an important character? All answers are legitimate, but they lead to different photographic places.

Speaking for myself, I generally want door #2. As a human, I see landscapes in human terms, and that liminal space where being human collides with the landscape is pretty compelling to me. That doesn't necessarily mean "people in landscapes", but it does mean I'm usually more drawn to a landscape image that has something to say about the human interaction with it than to one that doesn't acknowledge people at all.
