A growing part of the public is concerned about cities being designed and governed in a responsible way. In the contemporary information society, however, the democratic obligation of the citizens to inform themselves thoroughly, so that they can participate in public affairs has become impossible to fulfill. Rather than submitting to the opinions of self-proclaimed experts, citizens need new ways to make sense of what is going on around them. Accountability technologies stand for new innovative approaches to bottom-up governance: technologies to monitor those in power and hold them accountable for their actions.
