Ben Franklin's coin flip landed the wrong way - nowadays electronics circuits are calculated and drawn assuming movement of positive charges, when in reality it's the negatively charged electrons that flow.
Nothing wrong with saying that an absence of electron is moving. Both electrons and electron holes are just excitations in a quantum field anyway... ;-)
AFAIK, Electron holes refer to the P-type charge carrier in a semiconductor lattice where the absence of electrons behave similar to electrons in an N-type semiconductor. Benjamin Franklin was not concerned with solid state physics rather he's referring to the charge carrier in a conductor being positive when we later discover that its negative (electrons). When current flows through a conductor its just electrons (not holes) moving from negative to positive.
