From microblogging to picture sharing, from political news to peer-based language lessons – Social Networks (such as Twitter, Snapchat, or alternatives in educational contexts) have developed enormously during the last few years. These kinds of technologies are not just interesting within the context of private affairs, but they can also generate an additional value for the benefit of modern (informal) learning – both at schools and universities. In debates about an appropriate education of our following generations, the subject of Social Networking Sites (SNS) is never missing. Schools are increasingly tasked to integrate SNS in practical classes and to be open to new practices in education.
