The use of social media in academics' lives is well documented; however, researchers have a limited understanding about whether, why and how academics' social media use changes over time. Through interviews with 12 scholars, we identify multiple reasons that lead them to change their use of social media over time. Specifically, scholars report their social media use changing as a result of personal life events; professional transitions; concerns related to online privacy and self‐protection; evolution of technology; their desire to develop and nurture relationships; awareness of the needs of others; and, the political climate. These findings reflect individual desires and broader cultural shifts, indicating that scholars’ use of social media is impacted not just by their individual preferences, but also by forces that impact upon them.
