DOF for landscapes

I generally do not exceed f9 with the D800 because it resolves the effects of diffraction too well.

I suggest you learn to use hyperfocal focusing. I have an app for my iPhone.

When settiing the focus point for hyperfocal distance you maximize you foreground/background focus.

That being said, just because everyone shoots landscape stopped way down does not mean that you always have to follow the crowd. Consider what your subject is and how a shallow depth of field might create an unusual effect that distinguishes your work.
