Social media platforms and digital networks have enabled professionals to communicate with colleagues, disseminate information, and co-create knowledge. As the Internet has grown up and social networks have scaled, there is an increased awareness of the occupational impact of being online. Prior research in postsecondary education has examined the structure of social networks, imagined audiences online, openness of practice, and informational/communication patterns of academics. We conducted 92 semi-structured interviews with higher educational professionals beyond the faculty/academic role to understand motivations and challenges online. Participants shared how they navigate digital identity and contribute to networked practices in professional online communities. Multiple factors influence and impact the use of social media over time, specifically as professionals reflect on their digital presence, network affiliations, and informal learning opportunities. We identify seven networked practices: kinship in community, self-directed learning, digital norms, navigating context collapse, career advancement, reputation management, and risk versus reward assessment.
