This study explores the role of social media in social change by analyzing Twitter data collected during the 2011 Egypt Revolution.

In this article, the authors first provide a practical yet rigorous definition of crowdsourcing that incorporates “crowds,” outsourcing, and social web technologies. They then analyze 103 well-known crowdsourcing web sites using content analysis methods and the hermeneutic reading principle. Based on their analysis, they develop a “taxonomic theory” of crowdsourcing by organizing the empirical variants in nine distinct forms of crowdsourcing models. They also discuss key issues and directions, concentrating on the notion of …

This exploration attempts to build an understanding of how preexisting hyperlink structures on the Web and different types of information channels …
