Well, I've certainly put a lot of thought into my posts. (I can't speak for bobrat, of course.)
And part of what I thought about was: Can this information i propose to give be abused? Is there any indication that it can be used effectively to develop some constructive suggestion?
And, no matter how I turned it, for almost everything I wanted to say, the answer kept coming back, "yes" and "no".
Now, I may have more experience inferring implementation details from behavior; and so I'm perhaps unusually cautious about giving behaviorial information that would allow implementation details to be deduced. (I realize that most people probably wouldn't infer what I realize I'd be implying, but we're not pandering to just the clever spammers either.)
Now, IIRC, the one concrete proposal you made that wasn't shot down for being "degenerate hooliganism totally incompatible with our progressive socialist state" was the idea of "semi-trusted submitters."
And as I see it, there are two problems with that. (1) We have no reason to believe that there are honest submitters who really will submit enough sites to build a reputation (we know there are dishonest ones, but, as you say, THEY try to AVOID building a reputation); and (2) We have no way of forcing editors to act on that reputation, assuming it were developed.
The vast majority of honest submitters (in our experience) either don't submit very many sites at all, or they become editors. And if someone were to learn the ODP guidelines well enough to place and describe sites correctly -- it would be absolutely trivial for them to volunteer to edit a small category and do a few edits a month, just to keep their hand in.
So, when this idea (or a close kin of it) was discussed internally, the final consensus was that we couldn't identify a pressing need for a "semi-trusted" category of people.
I think I implied all this before, but I may have been relying too much on all the implications that seemed obvious to me.
There is one other point where the Directory priorities differ from those of any conceivable submitter. If there are already, say, 3000 gift shops listed, then it is really a very low priority to get any more listed. After all, our customers will surely be satisfied with the selection we give! Likewise, dietary supplements, patent health nostrums, web designers, and many other categories with typically large backlogs. But each submitter cares about only one site on earth -- for them, that site is priority 1, 2, and 3, and there is no priority 4. This is a fundamental conflict of interest, and it won't change. They need to act on their own best interests, but they need to understand that we probably will not act in their interest: even if we do, it will be only as an accidental side effect. They may consider that a problem, but we do not -- and will not -- consider it a problem.
