In the extension of digital media from optional means to central site of activity, the domains of language, art, learning, play, film, and politics have been subject to radical reconfigurations as mediating structures. This book examines how this changed relationship has in each case shaped a new form of discourse between self and culture and illustrates explicitly the character of mediated agency beyond the formal separateness from lived experience that was once conveniently termed the virtual and which has come to influence common assumptions about creative expression itself.
