When I wrote about using social media for learning in 2013, (abstract at http://www.irma-international.org/chapter/role-social-media-tool-learning/74970/) the challenge then was how to adapt or restrain the "lawless" environment of social media for use in formal learning, while preserving its intuitive ease of use. In the years since, we're seeing that the community of users is adapting social media organically by synthesizing formal knowledge with user-generated knowledge as Vora's infographic demonstrates. The next challenge will be for organizattions to measure the impact of this user-mediated informal learning, and recognize its value. Then encourage and reward learners and employees for participating and engaging in both individual and communal knowledge-building as the path to performance improvement, continuous learning and career enhancement
