I have seen several times users attempting to use tags as a way of clarifying their question, and assuming that the question will be understood based on which tags were chosen. I think this is a bad way of both asking questions and of tagging - the question should clarify everything you need to know to understand the intent of the question, and the tag should just be a way of finding questions of a certain type. I don't think there are hordes of people trafficking the help-center pages, but perhaps a note should be added to the description of the purposes of tags specifically pointing out that this is not what tags are for:
DO NOT use tags as a part of your question. Questions are meant to be self-explanatory, and tags are meant to categorize them.
