>Are you saying that DMOZ is more a reflection of the individual and somewhat subjective tastes of all its editors?
Well, the first answer is: yes, it is.
And that's a good thing. really.
First of all, several thousand active surfers is a pretty good sampling of surfers overall -- Harris Polls can predict the winner in a very close election with that size of sample.
Second, it really doesn't matter if the project is biassed. So is MSNBC.COM; so is the BBC; so is the New York Times or The Nation or even The Economist. The point is: this is the project built by people who share this bias. If you have another bias, build another project: I personally believe that the web needs more indexing tools, because none of them -- not Google, not Yahoo, not Froogle, not the ODP, not MSN's freaking ultimate monetization of their captive audience, not Aunt Sadie's knitting or porn or antiquarian links page -- none are adequate for all purposes. The ODP has a unique bias, and that's good.
Third, insofar as the sampling is biassed (and it is, by self-selection and group-selection of participants), it's biassed in the direction of volunteerism: whether it's collections of information, publications, or even local charitable organizations. And ... surely NOBODY on earth would venture to say the web as a whole is drifting too far in that direction: so the ODP acts as a tiny counterweight to an opposite commercial bias. Now, you or I cannot speak for our OWN websites: commercial or charitable, we are too emotionally involved. But surely we can agree that of all those OTHER webmasters out there, the commercial spammers are ruining things for everyone -- that is, nobody would say that (aside from their own sites) the web is insufficiently commercialized?
Fourth, I've participated in many ODP discussions over the years. And one of the commonly expressed biasses is that the ODP should be comprehensive. It won't ever have every site; it won't ever have every relevant page on any topic: but I have seen thousands of editor-hours invested on topics that really didn't interest the editor: because what DID interest the editor was having a representative set of topics. I've seen Buddhists, Pagans, various flavors of Christians, and assorted other religionists work together to fill in gaps in our Religion categories; I've seen left-wing and right-wing editors, American and European, work together to make a comprehensive list of political parties across the globe. I've seen Texans, Tennesseans, Californians, and even Canadians working together to build categories in states none of them had ever actually lived in, for communities they would never actually visit. Even if the DIRECTORY bias were not unique, the PROJECT organization has harnessed a level of effort that nobody else, commercial or noncommercial, could have supported. That is not in spite of its bias: it is largely because of it.
So the ODP's is not a kind of bias for which I see a need to be ashamed. That it doesn't always live up to its bias -- that is a bigger concern.
