The paper explores the complex relationship between ICTs and engagement of young people. Drawing on empirical work conducted with young adults (20-35 years old) in 2008-2009, it looks beyond the typical characterization of a technology savvy generation, trying to understand how the Web 2.0 is altering their social and political participation. Whereas a large part of the debate regarding youth participation underlines their rejection of traditional institutions, Web 2.0 technology seems to provide younger generations with organizing and interaction tools that help them to create new ways of altering the social, cultural and political life at a global scale. Yet, if a large amount of studies are now stressing the importance of understanding youth engagement in an informational era, it is difficult to grasp how and if the web is changing young people’s sense of civic engagement. Very little attention is given to the evaluative weighting of alternatives, values, and meanings that motivate or impede young people to participate in specific actions for social change. Calling for a flexible multidisciplinary approach, the paper suggests the need to rethink engagement, participation and actions for social change. Rather than cynical, apathetic or disengaged technophiles, the picture emerging from our research reveals responsible young adults, marked by web networking and social mobility, who demonstrate great dexterity in the use of ICTs to promote values of justice and solidarity.
