Rashmi Sinha – The perils of popularity

A presentation given at Web Directions South, Sydney Australia, September 27 2007.

Rashmi Sinha PortraitCan web-based social systems with their wide reach, user-generated and user-filtered content harness the wisdom of crowds? Duncan Watts’ recent experiments reveal how popularity based web social systems can throw up fickle, random trends that are essentially unreplicable, and only tangentially related to quality. However, popularity as a way to filter information continues to rise in popularity – replacing hierarchical menus, overtaking tags, and even used in lieu of relevance. Rashmi will link decades of psychology research on group decision making and social influence to what is happening on the web today. She will discuss different models of popularity based filtering such as Digg and YouTube. What are ways to avoid the Watts dilemma – including Google’s model of sociality, tag-based social systems, and object-based social networks. She will present some principles for the design of web social systems and how there were used in the design of SlideShare and discuss how SlideShare as an evolving social system handles popularity.
