Why is it that some people think you will get more in focus when taking a picture of a mountain at f8 than at f4? The distance of the mountain does not change; it is infinity. Now if you had a flower in the foreground... now that might make a difference.

Well, the edges of an image are often rendered better at f/8 than at f/4 even if the whole image is at infinity.  So, it's not just depth of field that's the issue.  It's also the flatness of the field and how the lens performs away from the center.  Stopping down some (within limits) will often help all three.
