Internet studies research often concentrates on mainstream platforms, practices, and users at the expense of people and technologies at the margin. This article introduces a collection of essays that addresses the gap in research, taking a number of different approaches. Indeed, arguing for a diverse and multi-faceted understanding of digital technologies can take a number of forms, including studying platforms that are incredibly common yet rarely investigated, looking at practices that fall outside the scope of mainstream communication research, and investigating communities that are non-Western, non-urban, and/or non-heteronormative. Research in these areas is crucial in developing a broader understanding of online platforms, and for expanding theoretical frameworks related to technology, media, and communication.
