But things have changed a lot since DMOZ began in the mid 1990s. Since then, Google came along with very relevant search results, and they were kind enough to show the other engines how to produce such relevant results. That caused dramatic improvements, to the extent that top search engines have been able to provide very relevant search results for some time, and they provide a lot more of them than DMOZ is able to do.
That gave me a good laugh and anyone who wants an original website rather than have to wade through several thousand affiliate and syndicated sites to get to the first one will know what a load of nonsense that is. Google search results are determined to a large extent not on relevance but how sneaky and manipulative the webmaster and his/her agents are in fooling the algorithms.
When they can give results consisting only of original, non-affiliate, non-syndicated sites full of verified useful relevance then DMOZ will die, no question. But I can't see that happening in the foreseeable future. Till then we plough on doing what computers can't - knowing intuitively who the spammer is. You would be amazed how editors spot mirrors and affiliates, it is almost instinctive and you can't teach it because you can't explain it - you can only develop the instinct through practice. Another reason the less scrupulous spammers hate us - how do you develop a strategy to beat unexplainable instincts? Many have tried, all have failed.
The big difference is our idea of relevance and what webmasters would like our idea to be. DMOZ is the only place on the web where Ma and Pa sites get absolutely level playing fields regardless of SEO techniques employed and money spent. All they need is copious amount of high quality original material and they will get listed.
When will they get listed? That is the big question. We are enlarging DMOZ by a quarter of a million sites a year at the current rate. That figure is after removal of dead links which we have automated tools to assist us with. So more than that in terms of new sites added. The web may be growing faster but a great deal of that growth is in crap - affiliate travel agents, syndicated sites, etc. There is not a huge growth in what we are interested in - sites with copious amounts of high quality original material. The better the site, the more original the subject matter (e.g. not a travel guide or online casino or other spam-ridden sector), the more interest editors show for the subject (and they are a broad cross-section of typical web surfers), the quicker the review. Send us a site when 50,000 others have done the same on a similar subject and you may as well forget it. And we aren't bothered - if we have 100 original sites on that subject already listed, why do we or anyone else need 49,900 other variations on the same theme? We don't exist to provide consumer choice - same information, pick your source, we exist to provide a link to the information once - if you want consumer choice having got the information then use a search engine.
Tens of thousands of sites are submitted and listed with days or weeks every year. Others wait longer. There is probably (no proof but logic suggests) a correlation between the number of sites that exist on a topic and the average time for a site to be reviewed and the chances of that site contributing significant enough new knowledge on the subject to be worthy of a listing. Online travel agents and US real estate agencies - hundreds of thousands of sites, lots of spam, very few niches left uncovered = lower editor interest, lower priority, increasingly difficult to stand out as original, longer wait for review, much smaller chance of listing.
