The tag of a question should be useful to categorize the contents and support finding similar questions. Because all questions in this forum should concern MATLAB, the tag "matlab" is actually meaningless. I think this concerns "matlab code" also, although there are question, which do not concern "code", e.g. this one.
There is a high correlation between the "matlab" tag and a lack of information in the question, such that a meaningful answer is impossible or magic guesswork.
Do I miss the point of these tags? Is deleting the tags the best reaction?
Walter has asked last year, how to proceed, if the only tag created by the author is meaningless and there is not obviously better tag due to a lack of information in the question. Is "no_tag", "no_detail" or "unclear" useful then?
