Samenvatting

In this concluding article of the special issue on web 2.0 we critically discuss several of the effects of this trend. Is it always a good idea to let citizens participate in policy making through social media? Will Open Data only lead to positive effects? And will the co-creation possibilities of web 2.0 really dramatically alter the ways in which bureaucracies function, as its advocates believe? We also draw up an agenda for future research on the governmental effects of web 2.0.
