This thesis both draws from and contributes to the ongoing project of critiquing and reconstructing the theory of the public sphere; an undertaking that has been characterised as both valuable and necessary by Fraser (2005: 2) and many others. The subsection of theory variously described as ‘postmodern’, ‘radical’, or ‘agonistic’ informs an intensive practical and theoretical critique of the pre- and post-‘linguistic turn’ iterations of the Habermasian ideal, before culminating in the articulation of a concise and operationalisable ‘neo-Habermasian’ public sphere ideal. This revised model retains the Habermasian public sphere as its core, but expands and sensitizes it, moving away from normative preoccupations with decision-making in order to effectively comprehend issues of power and difference, and to allow publicness “to navigate through wider and wilder territory” (Ryan, 1992: 286). This theoretical framework is then mobilised through a critical discourse analytical approach, exploring three cases of hacktivist counterpublicity, and revealing the emergence of a multivalent, multimodal discourse genre capable of threatening and fracturing hegemony. The case studies are selected using Samuel’s (2004) taxonomy of hacktivism, and explore the ‘political coding’ group, Hacktivismo; the Creative Freedom Foundation and the ‘performative hacktivism’ of their New Zealand Internet Blackout; and the ‘political cracking’ operations carried out by Anonymous in protest against the Australian government’s proposed Internet filter. The analysis focuses on how the discursive form and content of hacktivism combines to function counterhegemonically; that is, how hacktivists work to provoke widespread political preference reflection and fracture the hegemony of the publics they are oriented against. This approach generates a fruitful feedback loop between theory and empirical data, in that it enriches and extends our understanding of new modes of counterpublicity, as well as providing a detailed account of the under-researched yet increasingly widespread phenomenon of hacktivism.

In diploma thesis Open Call I focus on unequal position of artists in current art world in which, despite the transparent practices like open calls, still persists the cult of name, the power of networking and personal recommendation. This topic I artistically process in form of practical artistic intervention, which is close to the tactics of 1:1 scale of Arte Útil - specifically by creation of software tool called Nomin. Its purpose is to support weakened or marginalized groups of artists. Nomin uses properties of email protocol SMTP to allow its users-spectators to send fake self-recommending emails - from email addresses of famous curators to the inboxes various galleries or other art institutions. During development of program Nomin and its technical background (software documentation, web page etc.) I followed the paradigm of free, libre, open source software (FLOSS) and also the methodology of agile software development in order to provide in this gesamtsoftwerk the users-spectators with fully functional, user-friendly software and give them possibility to influence further development of Nomin or directly participate on it. Created artwork is thus not a single artefact but rather a set of interconnected objects and practices grounded in the network of social bonds and behaviours which balances on the edge of institutional critique, useful art, participatory art and collective performance.
