I've been looking at and thinking about the quality project page on de:. (I would link to it but I've lost the URL! Anyone got it to hand?) A lot of what they do is simply tagging deficient articles. As well as tags corresponding to en:'s {{cleanup}}, {{stub}}, etc. (article-space tags intended to provoke work to allow their removal), they have ones that speak only of a particular national POV (German, Swiss or Austrian, with a flag on and a request to add detail for other places).
One that occurred to me was an {{unreferenced}} tag, for an article that does not have any sources, references or external links listed. I've just created [[Template:Unreferenced]], with the following content:
:''This article does not include its [[Wikipedia:Cite sources|references or sources]]. Please add references or [[Wikipedia:External links|external links]].''
I'm picturing this going at the bottom of an article, where you would expect to see sources or references.
Before I go wild adding this, what do others think of the idea?
