This document discusses the concept of "lightness" in culture as proposed by Paola Voci from the University of Otago. It defines lightness as cultural practices that escape the boundaries of legitimate cultures. It contrasts lightness with legitimate cultures, which have weight and influence due to endorsement from established institutions. The document addresses how digital and mobile technologies have enabled the spread of light, ephemeral cultural works created by amateurs. It argues that these light mobile cultures impact fields like art, society, and knowledge production in ways that challenge traditional views of where knowledge and meaning are located.
