Involvement in the sense of active participation takes place at both the real level and the virtual level. These different levels often co-exist side by side and serve different dialogue groups. PlanSinn pursues an approach of interleaving these different levels: borrowing from the methods of blended learning, blended participation denotes a contemporary form of involvement and co-decision in which conventional participative methods (such as workshops, citizens' forums) and e-participation (online debate, voting, etc.) are productively amalgamated into one flexibly timed and coordinated process. Success comes from reaching out to people, both at the real level and the virtual level.
