This paper explores the impacts of Internet use in civil society organisations (CSOs) in Indonesia. Using qualitative data gathered from a series of workshops attended by CSO activists, the study argues that the Indonesian social movement today has perhaps both shaped and been shaped by the use of the Internet in CSOs. Internet use is never simple and straightforward; it is multifaceted and often raises uncertainties given that many CSOs adopt and use the technology in a number of different ways. This challenge brings enormous opportunity for CSOs and the furthering of social movement once the technology is appropriated in strategic and political ways. Despite problems and difficulties, Internet use in CSOs has had significant implications both on the internal management of the organisations and on external aspects; particularly the dynamics of social movement in the country.
