Social Interactome (SI) is a research project through the Addiction Recovery Research Center (AARC) at the Virginia Tech/Carilion Research Institute. This center and institute are located in Roanoke, Virginia. The idea is to have an anonymous, online social networking support system that can be accessed by participants recovering from addictions. This system started with a desktop Web application based on the Friendica API, tailored to support research on best methods for providing support. It has a minimalistic design that provides appropriate functionality. This project follows the process of using responsive web-development in order to make the system mobile-friendly.
