This question (How to make a salad olivier) has been tagged as "closed" a few hours ago. Is there a community consensus that tagging closed questions with "closed" is something we're now doing? I suspect, given that it's the only question tagged with "closed" that it's not. I've had a quick search through meta to see if I could find anything one way or the other, but haven't been able to find anything.
My opinion is that the tag is entirely superfluous and I'll be reverting the change dependent on the response I receive to this question.
