But don't forget this: the majority of websites aren't listable. You might have to review 3, 5, 10, or 1000 websites (depending on the category) to add one listing. The ODP gets about 10-40 suggestions for every listable site.
I often wondered why they didn't "fix" this. Let's face it, 99% of "listed" deeplinks are added by an editor (wild guess), not by the submission process. I never quite understood why the "system" allows people to submit their site/url to 10K categories if they wanted to, along with each individual page. This would save an enormous amount of time and system resources by "fixing" this single issue. Maybe they have already fixed this or improved the backend in some way and I don't know about it.
DMOZ is the "best" directory out there in my opinion. It has its flaws in both management and execution, but the dedicated volunteer editors more than make up for this.
