Last week Amsterdam University Press released my book Bastard Culture! How User Participation Transforms Cultural Production. Published under a Creative Commons license, the entire book is available as download. The book is an updated and expanded version of my 2008 dissertation and includes a new chapter on the discourse on 'social media'. My aim in this project has been to deconstruct the ideological connotation of participation and to offer a pragmatic view on technology and media practices in digital culture.
