Eric Gilbert- Designing social computing systems around relationships
Relationships are the heart of social media: they make it *social*. In this talk, I will present two social computing systems that place relationships and networks (i.e., multiple relationships) at the center of their design. First, I will present our work on modeling tie strength (i.e., how strong a relationship is), and how it can act as a tool for both design and analysis. Specifically, I'll present We Meddle, a Twitter app that builds categories of friends by inferring tie strength. Next, I will present a second Twitter app called Link Different that is inspired by the structure of a single social network triad. Link Different lets its users know how many of their followers already a saw link via someone else they follow. Hundreds of thousands of people used these two systems. Grounding my argument in them, I'll conclude the talk by suggesting that taking this kind sociological approach to social computing suggests many new open problems for design.
