The Open Directory Project (ODP), commonly known under the DMOZ name is an AOL-owned web directory. Since its inception in 1998, it garnered widespread success due to its tolerant, open-source policies. This means that any website which features original content and provides the end-user with relevant information and resources can be added.
DMOZ works on a voluntary-based system, allowing users to act as volunteer editors on the topics or categories of their choice. While some bigger categories are already full of editors, you can still volunteer to edit listings in more specific, niche subcategories. Registration is, of course, free and has its benefits, aside from the responsibilities associated with it. People can add, edit and even remove websites from the directory if they’re accepted as volunteer editors.
The directory presents its categories on a very simple interface, mostly based on simple text alone. The search feature allows users to quickly find the resources they need. Like most other directories, it features categories like Arts, Reference, Shopping, Computers, Business and Science. All these categories have a number of subcategories, each in turn having, in most cases other, more specific sub-subcategories. The listing DMOZ provides includes a direct link to your website and, from what I’ve seen, the links are do-follow. Immediately after the link, a short description is provided about the website featured.
While it’s true that most descriptions are objective, there are some exceptions and the simple, short manner in which said description is presented gives little to the user in terms of information. This, in turn, makes the directory a place where it’s clear that people want to get their websites listed just for the back-link benefit. Also, along with the emergence of better and better search algorithms practiced by popular search engines, its use to the end-user is becoming quickly and, in my opinion, regretfully obsolete.
But if you want to get your website added, just send it over to them. If you have relevant, interesting and unique content, they won’t refuse to add you to their database.
