It is recommended to tag every question with at least one in the (vaguely recognized) set of tags that represent the subject areas of questions. These tags are sometimes referred to as “top-level tags,” but I would like to change this name if there is a better name.
The word “top-level” implies existence of a hierarchical structure. Since most tags are not part of any hierarchical structure, the word “top-level” does not make much sense.
Does anyone have an idea what they should be called?
Update: Let’s call them “area tags.” (Thanks to Kaveh for proposing this name.) It is a concise name which describes their nature pretty accurately.
