I've seen this suggestion before, and my opinion on the matter hasn't changed one bit: it's a concept that just wouldn't work.
We already have our Uploader group and I believe that to be quite sufficient as these users are trusted enough to be able to submit quality content without having their content sit in queue awaiting Staff's review and approval. As has been pointed out already, there are far too many people on WebFlake who have their own interpretation of a "null" and what would make an exceptional null. I for one, have no interest in seeing the WebFlake community promise become one of ambiguity. I also feel that it's a complete and utter senseless waste of time for Staff to have to continually review alleged "nulls" when we have an internal list of acceptable sources.
There are already trustworthy sources out there, and I believe that Staff (as well as our Uploaders) are more than capable of finding and sharing that content here.
I'm not opposed to leaving this topic open.. feedback is obviously always welcome, but if you're not prepared to defend your suggestion from constructive criticism Onlkyl, then I suggest you move on from this topic until you've grown a thicker skin.
