When you say "update" - do you mean rewrite/add new angles to the article in a DIFFERENT URL, or should you update the article using the same URL?
In a related question, what about gray barred pages that are actually good and original to the site? Should these pages be considered "lost cause"? Is it better to rewrite these pages in a new URL and hope that it will be better picked up?
