Editors that rely on Google need to dig deeper. They are not doing the ODP justice.
That really borders on a cheap shot at the editing community.
Do you really believe that ODP editors are so single-minded that they are only capable of search Google? If so, then the discussion is probably over.
Editors use a wide variety of sources to find sites, from voter pamphlets to bus stop graffiti. Google is simply a source. Site suggestions are simply a source. Bus stop graffiti is simply a source. Business cards jammed behind pay telephones are simply a source. Church bulletins are simply a source. Junk mail is simply a source. Web links are simply a source. other directories are simplya source.
Editors, all of whom are actually capable of independent thought, are able to decide what sources they choose to use for finding sites to list. They choose the source that best serves the type of sites they are trying to add and the categories where they are adding them. They do this because they care about the directory and the people who use it.
For that reason it is impossible and impractical for you, or anyone else, to try and dictate how an editor should go about adding sites. with 7,000+ active editors, there are, I can assure you, 7,000+ approaches to adding sites.
