>commercial imperatives will force the submissions system to change or to go, perhaps along with the current system of volunteering.
Change is always possible, and commercial pressures might well have an impact. I think the Marxist ideologues overestimate the extent to which commerce controls humans. But insofar as commercial pressure forces change, I'd agree with Marx this far: WHATEVER CHANGE WAS FORCED, WOULD BE TOWARDS A SYSTEM MORE RESISTANT TO COMMERCIAL PRESSURE.
And, once you start thinking about how that change might work out in this particular niche, you'd realize: IT HAS ALREADY HAPPENED ONCE, AND THE ODP IS THE RESULT.
I remember when every portal and search engine had its own directory, built by its own hirelings. Yahoo! was the pattern, but frankly, none of the imitations came close to matching it -- and yet attempt it they must do, or be less than a REAL portal.
OBVIOUSLY, two things are going to happen: (1) Portals are going to start pooling efforts, and presto! appears as if by magic but really impelled by commercial pressure -- Looksmart, Zeal, NewHoo! (And, just to remind the greybeards among us, many other similar efforts started, just in case these stumbled.) and (2) people are going to start looking for non-commercial motivations -- and so go Zeal and NewHoo.
The obvious winning combinations in this all included: (1) take commercial considerations out of the picture by using volunteers, (2) push commercial considerations downstream by allowing customers (that means HOSTING USERS, not webmasters, in case anyone has forgotten!) to add ads (or whatever floats their nest eggs) (3) Circumvent commercial pressures by harnessing other sources of human motivations: such as community, public service, challenges, curiosity -- thus avoiding the horrific commercial overhead of the traditional hierarchical management, which in many organized systems may absorb the majority of all income.
So it is no accident that the ODP is relatively immune to commercial pressure -- it is the most successful of all the attempts to create something that WAS immune to the commercial pressures that had crippled previous efforts to build something like this.
That's humanity for you: don't give up, work around the problem, even if the problem is malicious humans. There's nothing unique about THIS niche. In computer operating systems, Microsoft's criminally monopolistic behavior and commercial predation has resulted in a whole new breed of programming projects relatively immune to predatory price-fixing: open-source projects such as Linux, Mozilla, Apache, OpenOffice. In media distribution, every attempt by the RIAA pigopolists to shut down any alternative music distribution system (mostly by litigational harassment) has resulted in new systems more resilient to single-point failures, and therefore harder to use legal thuggery against. And "self-published" (samizdat) literature thrived under the most brutally and violently repressive dictator of the mid-twentieth century.
Other pressures, other changes, are certain. But it's the pay-for-quick-review, pay-for-inclusion, pay-for-click directories that are constantly sliding down the knife-edge between economic collapse and descent into ad-farm irrelevance. That's one direction it's obvious the ODP won't go!
