I always thought it would be an interesting gambling game where folks bid just like this site, but the prize is instead all of the previous bids.<p>So, if the bids are $1, $2, $3, $4, the $4 bid would win $10 (minus a % take for the house).<p>The more bids there are, the higher the return for the ultimate winner, so bids could get quite high once it gets going past the first 2 or 3 bids.
