Fuchs, Christian. 2012. With or without Marx? With or without capitalism? A rejoinder to Adam Arvidsson and Eleanor Colleoni. tripleC - Open Access Journal for a Global Sustainable Information Society 10 (2): 633-645. http://www.triple-c.at/index.php/tripleC/article/view/434 Abstract This paper is a rejoinder to an article by Adam Arvidsson and Eleanor Colleoni: Arvidsson, Adam and Eleanor Colleoni. 2012. Value in informational capitalism and on the Internet. The Information Society 28 (3): 135-150. Arvidsson and Colleoni’s paper is a criticism of and reaction to one of my own articles: Fuchs, Christian. 2010. Labor in informational capitalism and on the Internet. The Information Society 26 (3): 179-196. The 3 debate articles are contributions to the "digital labour debate", specifically to the question if Karl Marx's theory is useful in this context (Fuchs) or shall be discarded (Arvidsson, Colleono). My comments focus on 6 aspects of discussion: 1) Misunderstandings of Marx 2) Autonomous Marxism 3) Corporate social media and the law of value 4) Capital accumulation on social media 5) Finance capital and social media 6) Politics, alternatives, and social transformation -- Christian Fuchs Chair in Media and Communication StudiesDepartment of Informatics and Media Uppsala University KyrkogŒrdsgatan 10 Box 513 751 20 Uppsala Sweden christian.fuchs@im.uu.se Tel +46 (0) 18 471 1019 http://fuchs.uti.at http://www.im.uu.se NetPolitics Blog: http://fuchs.uti.at/blog Editor of tripleC: http://www.triple-c.se Chair of ESA RN18-Sociology of Communications and Media Research ICTs and Society Network: http://www.icts-and-society.net
