This actually brings up another question: why do pony doors have knobs in the first place? I know unicorns can use magic in place of hands, as shown by Twilight opening the door here, but not all ponies have that (in fact, *most* ponies don't have that ability). Considering hooves are terrible for grasping objects, I would think that houses in Ponyville would have different ways to open a door (such as using a sliding lock) that is better suited for Earth pony useage.
