API design is about communication between the API designer and its API users. Good API can be recognized by quality of the communication between the designer and the users. Does the vision of proper API usage (in header of the designer) recreates properly in heads of the users? If not, your API is probably suffering from a poor clarity. Do you users hack around your API - e.g. use things clearly stated as not being part of the API? Can you prevent them to do so? Those are question this essay is about to analyze.
