About the DMOZ editors
DMOZ, also known as The Open Directory Project (ODP), is a large, categorized directory of websites and pages, which is staffed by volunteers. Every website and page that is added to the directory has to be manually reviewed before it is included. Being listed in the directory is free.
Not many people actually use DMOZ for searches in the same way that Yahoo! is used, so the directory itself is of little value in generating traffic. However, its data can be freely downloaded, and any website, however small, can use it. One not so small website that downloads and uses DMOZ's data is Google. In fact, Google's directory is nothing less than the downloaded DMOZ directory.
This has some significant effects for websites that are listed in DMOZ. PageRank is an integral part of Google's ranking algorithm, and higher PageRank helps towards higher rankings. The PageRank within a website is increased by pages from other sites linking to it, and the higher the PageRank of the pages that link to it, the better it is for the receiving site.
A listing in DMOZ creates two significant links into a website - one from DMOZ (Google spiders DMOZ just like any other site) and one from the Google directory. Both of these usually have decent PageRank. Then add the links from the thousands of small sites that have downloaded and use the DMOZ directory, and you can see why it is usually quite beneficial for a website to be listed in DMOZ. Simply being listed in DMOZ can take a website from a Toolbar PageRank value of 3 to 4, and even from 4 to 5.
