This layout constitutes a butterfly ballot similar to the one that the genius Therese LePore designed for the voters of Palm Beach. The "++" sign is equidistant between the two radio buttons; if one punches the hole immediately to the right of the "++" sign one has actually voted to downgrade not upgrade.
I noticed that I was downgrading posts that I actually liked this morning. Shades of Democrats voting for Patrick Buchanan!
Let's get rid of butterfly ballots everywhere, starting right here on perlmonks.org.
