What does a member usually have to do when he sees a tag that clearly does not belong on SO?
Just now I've found a dead tag, with only two questions. Another abused tag seems to be code. They don't describe question from technical or any other side: seeing these tags doesn't help you to understand what's the question about.
Wouldn't it be useful to have some kind of 'remove tag' voting system, just like 'tag synonyms' we have now? Or is it supposed to be handled in other way?
PS I can't check all 187 questions for code, so I'm not claiming there're no valid usages for it.
