antisocial notworking is an online repository of projects that explore the pseudo-agency of online social platforms. It takes a number of recent software projects as its inspiration to reflect upon the fashion for ‘participation’ within the arts sector and culture in general. The concern is how the Internet is increasingly characterised as a ‘platform’ (or collective machine) for ‘social’ uses, but to question what is meant by the terms in such descriptions. Although social networking platforms rely on user-generated content, what is the nature of this participation? What alternatives (or antitheses) can be identified? For After the Net, antisocial notworking features a selection of installations: logo_wiki, Wayne Clements (2007); Participation 0.0 - Part I, Linda Hilfling (2007); www_hack, Rui Guerra (2008).
