The document discusses social collaboration using SharePoint. It defines social as a gradient ranging from implicit networks to fully crowd-sourced collaboration. It highlights how SharePoint 2010 enables social connections through profiles, presence information, notes, insights into organizations, and social networks. It allows for social content like blogs and wikis, social feedback through ratings and tagging, and social search based on relevance and social distance. The document presents TeamPark as a trajectory for SharePoint implementation with four phases - awareness, strategy, implementation, and achieving an active collaboration platform. It notes that in reality, multiple implementations and platforms can be active simultaneously while awareness and strategy phases may be discounted.
