Social software has emerged as one of the most exciting and important phenomenon in today's software and business arena. With social software, individuals can interact, share, and meet other individuals, presumably with similar interests, forming large data, knowledge, and user bases. Examples of social software include content management systems such as blogs, knowledge and collaboration management systems such as wikis, social networks such as MySpace, user content sites like YouTube, social bookmarking / folksonomies such as, instant messaging, videoconference tools, etc. Social software engineering, in turn, can be defined as the application of processes, methods, and tools to enable community-driven creation, management, deployment, and use of software in online environments.

The social software movement can be regarded as both a challenge and an opportunity for software development. On the one hand, social software itself brings its own kinds of challenges such as data sensitivity, content legality, scalability, and performance. On the other hand, the social software movement is apparently causing a fundamental change in the way software engineering is practiced, benefiting from the technologies and experiences gained from Web 2.0 and the expectations of the forthcoming Web 3.0. In the near future, various forms of social software development will become a reality. Examples include software mashups, intelligent context-aware software downloads, and online cooperative CASE tools. Such a cooperative model of software development would also meet the challenges of contemporary software engineering such as outsourcing, offshoring, and open source software.

The second edition will build on the success of SoSEA 2008 and discuss the latest trends in the field of social software engineering. Focusing on technology issues, the workshop will offer an opportunity for the participants to share experiences and discuss challenges involved in building and using social software. A special emphasis will be put the role of social software concepts and technologies in shaping up future software development. The workshop will also identify key research issues and challenges that lie ahead.
