Social networking sites allow people to share experiences and stories through new forms of online communication. This blurs distinctions between physical and virtual worlds as people increasingly live hybrid digital and offline lives. Such sites provide spaces for self-expression and community building around shared interests. They also incorporate elements of games through reward systems that keep users engaged. Going forward, social networking is likely to proliferate and blur boundaries further as broadcast and games converge, giving people more ways to both consume and actively participate in interactive narratives across physical and digital spaces.
