What's wrong with the plain "vote for 5 or fewer candidates" method (5 as that's the number we want, fewer so people don't just fill in the gaps with people they don't know anything about).
Shouldn't this accurately represent the wishes of the community. I don't really see why we should rank the choices, which has uses when you're electing and wish to also know the positioning of the elected.
Then again, I don't know anything about voting theory so please do shoot me down
