We conclude that there are manifold ways of using social software for RE. Dedicated RE tools based on social soft- ware allow the involvement of end users in the RE process. However, these tools might still require end user train- ing and other additional effort (e.g. registration) before RE activities can take place. Apart from dedicated RE methods and tools, researchers and practitioners are using existing social software to support RE and SE activities. This means that instead of providing methods and tools which are fully based on using the functionality of an SNS, those functionalities are only used in part to complement existing processes. We conclude that current attempts to use existing social software tools in an RE context are still in an early stage.
