We can say dmoz is father of all other directories.your site will include in about 1200 other web directories including google.you will see in boost in your PR once your site accepted in dmoz.These ODP links are treated like gold by Pagerank™. It doesn't even matter what the individual PR of the category page is. I have seen sites gain a large PR boost on the toolbar as soon as Google updates it's directory with the latest one from dmoz.org
