The focus on technological principles distinguished our work from prior research in this area, such as that explores the potential of Web 2.0 for education in general or [6] that describes the Web 2.0 principles for an educational audience .
Secondly, we intend to show that Web 2.0 is not only well suited for learning but also for research on learning: the wealth of services that is available and their openness regarding programming interfaces and data allow to assemble prototypes of technology-supported learning applications in amazingly small amount of time.
