As a dmoz editor, I will admit it is hard to sometimes get listed in the directory. But the thing is, you aren't really understanding the concept of suggesting a site either. In the eyes of dmoz, when you suggest a site, you are simply doing just that. Suggesting a site. There are no requirements saying that editors MUST review sites in queue. All of the sites in queue are sites that have been reccomended for the directory. Editors are encouraged to list sites that are unique in content. Now with all of this said, one of the very popular categories I edit in has over 5,000 sites in queue. Now lets say I review 100 of them in 1 day. Then that same day, people suggest another 500 sites. It is really a never ending battle of keeping up with the queues. I will tell you this much, read the submission guidelines. If you suggest a site and follow the guidelines on how to write a compliant site description, an editor may tend to approve your site faster since he/she may not have any editing to do on your suggestion. I often look through my queue to see if any are ready for approval right away. Then I go back to the others that need work and have to modify the wording of descriptions, etc. You have no idea how many people try to suggest sites with keywords for a description. The idea is to describe the site. Nothing else. You also need to realize how active an editor is as well. Volunteer editors are only required to login once every few months and perform an action to keep their accounts active. Some editors may only login and review 10 sites a day, some may login and review a couple hundred a day. There are awards and incentives for being very active and helpful, but they are only there for those who wish to compete for them.
As for dezinerite, I don't doubt there may be some editors performing some type of abuse such as taking bribes. But those editors are breaking rules since this is against ODP guidelines. If you run into a "cranky" editor abusing the policies, you are more than welcome to report them. All reports of abuse are investigated and the editor will be taken care of accordingly.
So to summarize, suggesting a site is no gaurantee of review or approval. Suggesting a site is simply just that. A suggestion. So the best way to look at this is to suggest your site and forget about it for a while. If you are listed, great. If not, don't stress over it. The directory is created by humans for humans. There is no way a human can possibly list every site on the internet like some of the automated search engines possibly can.
