I found plenty of useful links, if anyone checked these regularly we will have quality control. Plus a few unheard of pages won't be duplicated so much later down the road. By order of importance and I give a reason:
These pages can cause missed opportunities[]
Special:LonelyPages : There are no links from another page, meaning we have the least information about these pages.
Special:WantedPages : These pages are being linked to although they have not been created, meaning they're being referred to and linked to but not fully understood.
Special:ShortPages : need more information.
Special:UncategorizedPages : The hardest sources to gather info from are uncategorized.
Special:DeadendPages : Pages that have no other links in them.
Special:FewestRevisions : Quality is "?"
These are minor details, and can be improved to an extent[]
Special:WantedFiles : Files that are named, but don't exist.
Special:WantedCategories : Categories that are linked to that lack a description.
