Hey All, I'm writing on behalf of Sweta, who is a graduate student at Purdue University. Sweta is cc'd on this email. Sweta would like to do a comparative case study of the structure and rhetoric of pre- and post-disaster social networks in Nepal and Puerto Rico. Specifically, Sweta has the following questions: 1. What is the best method for collecting pre- and post-disaster data on social media? 2. Is it possible to collect data not just on Twitter but also on all social media platforms (e.g., Facebook, Instagram, LinkedIn)? 3. Which social network analysis (SNA) tool has the easiest learning curve and is the easiest to use to analyze relational structures on social media? I truly appreciate your help and advice, and I look forward to hearing from you. Thanks, Yosem
