I have been an editor for the DMOZ for about a month and I edit only one of the low level categories. Here are some things to remember when submitting your sites.
1. Search for the right category before submitting. If you submit to the wrong category the editor will need to search for the right category when he/she has time then re-submit it to another category for review and the process is repeated.
2. Read the guidelines very carefully the more you edit the less we have too. I add sites that already are to guidelines before I go back and have to redo the others.
3. When writing your descriptions don't add fluff or hype of any kind just state how your site is unique and what can be found there. For examples read the descriptions of sites that are already in your category.
4. The title needs to be the name of the site not keywords.
5. Some categories don't have full time editors or the editors are not active daily so volunteer to be an editor. Follow the submissions to become an editor exactly. Their looking for active editors not just someone who wants to add their sites and leave. When I became an editor the category had not been edited in a while and there was a back log of sites that needed editing.
6. Look at your site and imagine that there are no ads and no links just content. Now if the content is unique, can not be found somewhere else, and can stand on its own then you will most likely get added just be a patient!
7. As an editor I am tasked with finding sites that have unique content that I can add to my category. So if you have great content the editors will find you.
Hope that helps!
