To be clear, I don't think the wedge product is sufficient either; I just think it's the real reason most people end up finding GA to be appealing.
I think there's work to do to clean the whole space up. Particularly, the wedge product is a 'join' or 'union' operator (amusingly, it has the wrong symbol). The 'meet' operator is not widely known but should probably be equally prominent. I haven't figured out for myself where the other holes are yet.
