Quite a lot of landscapes, where nothing in the frame is "near" the camera, will have everything be in focus both at f/8 and f/22. The only likely difference will be that the f/22 shot is softer, due to diffraction, as described by Peter Zack.
It makes more of a difference if you have something close in the foreground and a far away background, but even then, for short focal lengths, f/8 is often enough.
I have "Understanding Exposure" by Peterson, and he seems to recommend f/22 and other small apertures for a lot of landscapes, but that probably isn't the best advice a lot of the time. Of course he does also point out he virtues of f/8 and f/11 etc. Sharpness isn't always everything either.
