This paper discusses the results of a survey on a concrete case of eParticipation, i.e. a campaign to get teenagers to participate in the Youth Council of the City of Lausanne. We analyse both the traditional tools (billboard ads, newspapers, official communication through schools) and the online tools (Web page, Facebook, YouTube). During our survey we used mixed methods: an online questionnaire (1360 respondents), documentary analysis of the Youth Council candidates’ application files, and interviews. We then analysed the impacts of the campaign in terms of participation under different angles, amongst other diffusion channels and use of humour.
