DMOZ is run by human editors who are volunteers. I edit a category with over 700 sites waiting to be reviewed. My category already has over 300 listings, many done by a previous editor who didn't follow guidelines very well. So I not only have numerous sites to review but a pretty large category to clean up. Many of the sites I am getting to have been in the queue for over 2 years. That is just a glimpse into what your listing may be up against.
