Introduction: Marginality and Social Media

This special issue brings together 13 manuscripts and two practitioner responses that speak to the intersection of marginality and social media in a variety of contexts. Readers of Social Media + Society certainly know what social media are, but marginality may be more elusive. We introduce this special issue by noting the historical moment for studying marginality, providing a working definition of that concept, and highlighting how this special issue sustains and extends that conversation within the context of social media.
