I think I have a reasonable method of cleaning up many of the leftover pages in the main namespace that should be moved to wikipedia: or meta (most of which have already been moved, but still exist). But before I do this I want to give the group some warning and ask if anyone has concerns.
I think it's important to actually delete these for several reasons. One, they distort our statistics; they make it appear as though we have more real articles than we do. They show up in searches. They also make the utilities of the new software like orphan pages less useful. Second, their existence is confusing to new users and might encourage the creation of more such articles in the wrong namespace. Finally, having the articles in the right namespace should make it easier to update and consolidate them, as many of them are badly out of date.
I'm looking at things like "Wikipedia commentary/*", most of which have been moved to meta but still hang around, and things like "Wikipedia Announcements", "Wikipedia FAQ", etc.
But before I go about removing these and fixing links to them, I want to hear if anyone has reasons to keep some of them in the primary namespace, or other concerns. 0
