You also need to distinguish between the contexts where you need addresses versus coordinates. Lat-longs, plus codes, and word-encoding schemes are all coordinates -- they identify a point or area on the globe. Addresses are last-mile navigational instructions. "Apt D, 123 Main St" allows anyone with local knowledge to navigate efficiently to the location indicated: first they drive to Main Street, then they proceed along the ~monotonically numbered parcels to 123, then continue to the apartment labeled "D". The advantage of coordinates is that they don't require local knowledge and can identify arbitrary points; the advantage of addresses is that they encode instructions for land navigation that takes into account which parts of the land are passable.

Sheesh, lightening and lightning? Not to mention, "instants" when "instance" is also a valid word.
