This article explores the participatory space for political debate opened up by social media in Vanuatu with reference to the implementation of a recent language-in-education policy, jointly funded by the governments of Vanuatu, Australia and New Zealand. Although Vanuatu appears to have been debating the same language issues for several decades, what is new is the level of participatory engagement in political matters, with the Facebook group Yumi Toktok Stret (YTS) providing one platform through which democratic citizenship is established and negotiated. Assay of a debate that erupted in the group in March 2016 discloses significant disquiet and confusion about a change to the medium of instruction in early primary education. It is asserted that social media provides an invaluable insight into the extent to which the general public understands, feels consulted about and supports policy change. The debate on YTS also displays that the Government, its international development partners and technical advisors would be well advised to pay attention to such debates, and engage with social media as a new mediated “think tank” through which new policies can be democratically discussed.
