About 4 years ago (may not apply anymore) I ran a fairly popular site about deafness.. Got thousands of hits, yadda yadda. Lot of editorial content. Anyway, I submitted it to Yahoo, as did a couple of my visitors, and we never got it listed. A YEAR after the site was shut down (ISP/Host went out of business), they list it. I stumbled across it somehow and it had been labeled as a new entry. 6 months after I notified them it's a dead link, they removed it.
