SSE has been organized successfully in Munich, Kaiserslautern, and Paderborn in conjunction with the Software Engineering conference (SE'08, SE'09, and SE'10). In 2009, we merged the original community with the community of the SENSE workshop (Software ENgineering within Social Software Environments). In 2010, we merged the new community with the SoSEA workshop (Social Software Engineering and Applications) held at ASE'08 and ASE'09. For the 2013 SSE in St. Petersburg, Russia, SSE merged with the web2SE workshop held at ICSE 2010 and ICSE 2011. SSE'14 was collocated with ESEC/FSE 2014 in Hong Kong and SSE'15 was collocated with ESEC/FSE 2015 in Milan.
