End User Development and Meta-Design

The first decade of the World Wide Web predominantly enforced a clear separation between designers and consumers. New technological developments, such as the participatory Web 2.0 architectures, have emerged to support social computing. These developments are the foundations for a fundamental shift from consumer cultures (specialized in producing finished goods) to cultures of participation (in which all people can participate actively in personally meaningful activities). End-user development and meta-design provide foundations for this fundamental transformation. They explore and support new approaches for the design, adoption, appropriation, adaptation, evolution, and sharing of artifacts by all participating stakeholders. They take into account that cultures of participation are not dictated by technology alone: they are the result of incremental shifts in human behavior and social organizations. The design, development, and assessment of five particular applications that contributed to the development of our theoretical framework are described and discussed.
