Socialstream. Socialstream is the result of a Google-sponsored capstone project in the Master's program at Carnegie Mellon University's Human-Computer Interaction Institute. This project was guided by three goals that built upon each other: Initial Task: Rethink and reinvent online social networking Refined Focus: Discover the user needs related to social networking and explore how a unified social network service can enhance their experience. Prototype Goal: Create a system for users to seamlessly share, view, and respond to many types of social content across multiple networks. Directed to help improve the online community orkut, the project's scope was not to simply redesign the interface. Our team considered how online social networking could bring greater value to users, especially for ages above twenty.
Socialstream is our response to these needs; it is the result of a rigorous user-centered design process that involved formal research and evaluation with over 30 participants.
