Based on three dominant traditions meeting there--public (municipal) decision-making, Web 2.0 and participatory design--we identify challenges and solutions regarding participation and engagement of municipal workers and citizens. While this intersection is exactly where a new form of democratic participation could develop, the three traditions were, nonetheless, far from easily combined in the specific cases. The challenges that we have identified are to: Identify win-win situations, rather than to maximize participation; to work with motivation for long-term projects across municipality and communities; to identify and work with early movers, and not just representative citizens; and to create space for local municipal agencies to develop bottom-up technological solutions. The multiplicity of co-existing traditions of involvement need more focus in the future development of participatory design.ene-governmentmunicipalitiesparticipatory designweb 2.0Text/Conference Paper10.1145/2768545.2768546
