Actually, ODPs policy towards deeplinks has evolved quite a bit over the last several years. When the directory was young, and we were still trying to find content that would help us flesh out the structure, deeplinks were viewed as a good way of doing so.
Over time, deeplinks have proven to be less and less useful. Where we once embraced deeplinks, we now shy away from them. We are particularly gunshy when it somes to webmasters who are suggesting their own sites for deeplinks. A very high percentage of those suggestions are worthless because what is hugely different to webmasters (brown shoes versus black shoes) is all the same to us.
"But you don't understand," they cry, "brown shoes are not at all the same thing as black shoes." To which we reply (via the delete button) "we do understand, for our purposes they are all shoes. Shoes and airplane propellers are what we usually think of as different."
Indeed, some of the best current sources of deeplinks are from places where the webmaster doesn't think about links, or SERP or page rank or any of those types of things. That means places like Geocities, and Tripod, and The Government of France, and The Red Cross. Those are places where the focus is on getting out great information, not on web page rankings or cost of sales.
So when Acme Tool and Die submits deeplinks for
www.acmetoolanddie.com/metric
www.acmetoolanddie.com/SAE
It takes us about 1/10th of a second to bounce one or both, especially if we know that
www.acmetoolanddie.com/ is aready appropriately listed.
Similarly when
www.hotelreservationsareourlife.biz decides to submit
www.hotelreservationsareourlife.biz/Alabama
www.hotelreservationsareourlife.biz/Arizona
www.hotelreservationsareourlife.biz/Arkansas and so on, we end up with 50 or so different editors all independently coming to the same decision -- the deep links end up getting rejected.
