...from the maker of The Million Dollar Homepage. He has a new venture called Pixelotto, where you essentially buy pixel space as on the prior site. Users hitting the site register with it and agree to click at least ten ads a day. Once the ad space is sold, an ad is chosen and a winner is chosen from the list of end users who clicked on that ad.
Genius, again. The ad makers get clicks, the end users get entered into a lottery, and the site maker makes money.
