In doing so, we learn that both domains share further common traits, including similarities in IT structures, knowledge generating capabilities, presence of intermediary service providers, and techniques designed to attract and maintain participant activity. Stemming directly from this analysis, we discuss new directions for future research in both fields and draw out actionable implications for practitioners and researchers in both domains.yes10.5210/fm.v20i12.6143http://firstmonday.org/ojs/index.php/fm/article/view/6143http://firstmonday.org/ojs/index.php/fm/article/view/6143
