“The words metaphor and intuitive are often used in UX. They are the metrics that we use to judge the quality of a solution. But is this quality really as universal as we might like to believe? (…) Understanding something intuitively really means that you understand it holistically. If you understand it holistically you can fill in the gaps. This doesn’t mean you shouldn’t make your design intuitive or improve on it, not at all. Just understand that you are doing it for the natives not for the noobs.” (Thomas Petersen ~ Black&White)
