I can't believe anyone actually ever used them - who goes to a site to browse the ads? And even if they did, it was hardly intuitive.
Ken_b, I think you'll still see one ad showing in a 300x250 if the advertisers outbid the total of the next four ads. Could be wrong, but I still see em now and then, and I know there's lots of ads available.
