Postings on this site contain two radio buttons side-by-side. The symbol "++" is equidistant between the two, with the symbol "--" to the right of the rightmost radio button. To vote to upgrade or downgrade a post's "reputation" a user selects one or the other and then presses the vote button.
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.
