Official ODP Guidelines: Cool Sites - Definition: "A site that stands out among the other sites in the category or is the most definitive site on a subject can be marked as a 'Cool Site'. Ideally, since the cool site is the best site in the category, there should only be one. However, two cool sites may be appropriate in some circumstances. It is contrary to ODP policy for editors to cool their own sites or any sites with which they are affiliated. Doing so is grounds for removal."
