This is one of the most common, and perhaps most pernicious ODP myths. And I've asked, over and over again, just WHAT people think might be missing that we could tell them about?
Nobody has ever even tried to answer. The only answer that would make sense, of course, is "unique content." But there's nobody on earth who is in a better position to know what is unique about the site's contents -- than the webmaster.
Does the site have unique content, but the navigation fails to make it prominent enough for the reviewer to find? Does the webmaster have any unique content to post, but perhaps hadn't posted it yet? Does the webmaster have no unique content to grace his name? WE CAN'T KNOW. But the webmaster does. So, what are people asking us for, and why?
