The Short Answer
Very little would happen if you operated a microwave with an open door. Microwaves are notoriously hard to get into the food that you're trying to cook, which is why most microwave ovens have a rotating tray, to try and align the food with as many microwave paths as possible. If the door were open, the energy would dissipate almost immediately. On Mythbusters, they once tried to make a microwave "gun" with the magnetrons from three microwave ovens, but were unsuccessful, even with that amount of overkill. Sticking your hand into an operating oven, though, is a different matter, so better safe than sorry.
