However, a wholesale avoidance of submissions based on quantity is just as likely to hurt ODP moving forward, as it likely misses relevant sites along with spam
This assumes there's no other way of finding relevant sites.
But site suggestion is only one way, and not the most important.
The fact is, a wholesale avoidance of Google searches is likely to hurt ODP, as it WILL miss relevant sites.
The fact is, a wholesale avoidance of personal link collections WILL hurt ODP, as it WILL miss relevant sites not contained in Google.
Each editor has the right to judge what methods of finding websites are most efficient ... FOR THE SUBJECT HE'S CURRENTLY WORKING ON. We know perfectly well no one method works perfectly, and editors are expected to develop skills with multiple methods, and use them to build categories.
But ... nobody has a right to criticize any editor for NOT using any particular approach. Nobody can tell anyone else to use MSN-Undead Search instead of Google! Editors share techniques they have tried, and found effective based on that experience. And if any editor feel other editors are neglecting some method, he can simply repair the neglect by USING that method and publicly demonstrating how well it works -- by finding lots of good sites.
You're talking to editors who have, collectively, found hundreds of thousands of sites, and who have been discussing search procedures with editors who've found millions of sites. Any time you want to stop speculating about how to find websites effectively, and start learning -- you know where to come.
