If you only ask questions about dictionary use, then you will exclusively get answers like those that characterise the filled in questionnaires of the commercial publishing houses. They produce dictionaries in order to sell them and earn money and, therefore, they conceive them in such a way that users that might have a bad dictionary culture feel that the dictionaries meet their needs. In doing so, you generate inbreeding and block the necessary innovation. This is the unavoidable result of a practice that pays excessive attention to the study of existing dictionaries and doesn't endeavour to produce new concepts and to introduce a new dictionary culture. It is, in other words, a poor lexicography.
