Could you tell me the criteria that it has failed against, because to fail you have to miss your targets. Quotes from DMOZ site about objectives will be acceptable. You may believe it has failed, refer to my earlier comments about opinions, but, sorry to keep reminding you, as you told us earlier if two or more people tell you something and hundred tell us we suceed. But I debate that as a mute point. We did not set up to get used by Google or downloaded by thousands, we set up to serve the purpose of human editing a directory of unique content sites to serve people who wanted such a directory, we have produced the largest such. Where have we missed our targets and thus failed?
It just seems bizarre to bury your head in the sand and loudly proclaim "nothing is wrong" when the truth of the matter is that DMOZ has failed and will continue to be a failure unless massive management and cultural changes are made within the organization.
If you really just enjoy categorizing sites, why not start your own directory (preferably a niche directory) or volunteer at a large directory like BOTW? There's really no sense in investing more of your life into a failed project and then trolling forums looking for people to defend that failed project against.
