C'mon Yahoo, get on the ball. I just checked a certain category where a site of mine is listed. Over a year ago I noticed that another site in that category run by someone else was listed under a URL that the site hasn't been at for nearly 4 years. I submitted an update on behalf of that site giving the current URL. (This is an amateur site with a free listing the current webmaster may not even be aware of.) Still, to this day, that site is listed at the dead URL.
With all the money the Yahoo directory makes, I expect better. No way as a volunteer ODP editor I'd ignore for over a year a URL update submission. And the cat space I can edit in has over 3,000 listed sites. (The ODP considers keeping the cats free of improper listings over dealing with sites in unreviewed.)
