The document discusses blended facilitation, which refers to facilitating group development using both online and offline tools in a structured framework. It provides the example of the Media Sandbox case study, which used a blended approach to facilitate collaboration and knowledge sharing among an online community of practitioners. Key elements of the blended model included online knowledge assets and discussions, as well as in-person workshops and events to launch projects, share lessons learned, and build community. The blended approach aimed to create an open community that facilitates long-term innovation, knowledge sharing, and learning through both virtual and physical interactions.
