As described here http://www.mediawiki.org/wiki/Extension:Flagged_Revisions#Reader_feedback only users that are not editors can rate articles. On dewiki there have been protests, because most editors also read articles, so they are also readers. It doesn't make much sense to disallow feedback for them, as they can just log out and give their feedback anonymously.
