skillMap serves the demands of 3rd generation KM for unstructured and human-centred approaches and is based on the Web 2.0 – concept. It combines a social network with a semantic network of skills. A visualization of the combined graphs serves as user-interface. After describing the technical implementation of the skillMap, we argue that the skillMap offers levels of variety, autonomy, creative chaos, and redundancy that are present in successful social movements of the web and fuel users’ intrinsic motivation. User evaluation results show that the positive perception of the user interface co-occurs with user expressions of enjoyment and curiosity.
