Every day, tens of thousands of domain names are deleted because their owners fail to renew them. Most of these deleted domain names are worthless, but some are extremely valuable as website properties or for their visitor traffic via incoming links or search engine listings.

Yoid.com lists these deleted domain names that are available to be registered. These are not "pending delete" or "on-hold" domains that can cost hundreds of dollars to acquire in a bidding war, but domains that can be registered right now.
