As you know, we annotate posts with "citation-needed" notices when they don't reference any sources.
What you may not know, is that there is a list of such posts available here, visible to everyone!
What do we need to do with it? Simple: let us review the notices!
If a post has a notice, but also has sources in it, it's probably been fixed
Please review the sources and vote appropriately. If you feel that the post has enough support, flag it for mod attention with the comment
If a post has a notice and no sources, and the post has not been touched after May 1st 2012 it's probably been abandoned
Please consider if you can add sources yourselves and/or vote appropriately. If you do not put in sources, flag the post for mod attention as
abandoned. If you can, you may want to vote to delete the most egregious bad examples at this point.
If the post has been touched since May 1st 2012, vote on it as you deem appropriate, but do not flag for mod attention.
This should allow us to remove some of the notices, give credit where credit is due and do a general clean up of answer that need some love and attention.
