Not to sound like a broken record or anything, but...
We've submitted over 30 client sites to DMoZ in the past 2+ years. All of the sites are very well designed sites with quality content. All of the sites have been under review for at least 1 year and many for more than 2 years.
None of the sites has been listed with the directory or even reviewed. I've posted threads for each site on the DMOZ editor forums and followed up ever 3 months (now every 6 months) on each and every site. Still nothing has happened.
The way that DMOZ is run is mind-numbingly stupid. I can't believe that an organization like this is allowed to have such a signficant impact on the search results for the largest search engine in the world. Doesn't Google recognize that something must be done about DMOZ or web professionals will eventually turn against them?
One thing I'm interested in -- how do you learn who the category editor is for your categories or whether or not one exists?
