DialIdol

The Freakonomics guys (well, actually just Levitt) posted about DialIdol today. DialIdol is a dialer software that measures % busy signal for different American Idol voting #s, with the assumption that the highest % busy signal means “most votes.” So far they’ve been 65% correct in their predictions. Considering that you can actually wager on American Idol outcomes, i wonder what DialIdol has done to the odds.
