One I don't think gets talked about enough is approval voting. Vote for as many candidates as you like, whoever gets the most votes wins. Voting for all of them is effectively the same as voting for none of them. It also has the massive benefit for the general population that it's simple to explain. Even gives third-party candidates and moderate candidates a real chance at winning, since no one would feel like they're throwing their vote away by including them.
