Thanks @WildaBeast
The reason for this is to prevent runaway winners. It’s more fun for everyone if the votes are spread around a bit, and fun is the name of the game. In fact, I wanted to have people make ranked choices with 3, 2, 1 points for their choices, but the forum software doesn’t allow for that.
It’s worth noting that having three votes each was always the rules - it’s just that it’s only now that we have a single poll we can enforce it.
