Title: Surfing a web of trust: Reputation and Reciprocity on CouchSurfing.com

Authors: Debra Lauterbach, Hung Truong, Tanuj Shah, Lada Adamic

Description: Trust is valuable in social networks, even moreso when the social network you are a part of regularly involves meeting strangers, having them stay the night on your couch, and staying on other strangers' couches. In this paper we looked at the properties of the "vouch" network in CouchSurfing and consider the strength of such a system where reciprocation is the expectation.

In this study I observed and analyzed the network structure, diffusion and growth of the network over time of a Facebook application.
