i'll add another term for this.......'reverse supering'............

i think there are some benefits to it jim, i think it depends on your situation. as tec mentioned the placement of foundation on the bottom of the stack.
myself, i top super most of the time. i use top and bottom entrances, and like dave i do use an excluder because of the foundation-less frames for comb honey, and like dave, i don't like the queen laying up in the supers. i only extract once a year, so supers are added as needed, in good years, it is not uncommon for me to have up to 6 supers on, so reverse/bottom supering would be very tedious. i do keep track of frames being drawn and filled, so will rearrange frames as necessary, or if a flow is waning or a box is being somewhat ignored, i reverse super the box.
