The crisis of trust, that the occidental democracies currently experience, compels to think anew about the position that the citizens occupy in these ones. Indeed, the citizens have to be placed again in the central position so that they participate more actively in the deciding process. Thanks to that, the democracy will become anew the true expression of the general willingness. If this doesn't happen, the citizens will continue to withdraw from the traditionnal political organisations and will take part in peripheral ones, such as the transnational social movements. And these movements seem to develop a way of operating and a political ideal close to the participatory democracy and to Internet. Therefore, a coincidence between a political paradigm, an organization and a technological object emerges. Consequently, this connection has to be verified. Moreover, thanks to the study of their information posture, we have to determine if the reference to the participatory democracy is a constitutive characteristic of the transnational social movements.
