Continuing The West Wing in 140 characters or less: Improvised simulation on Twitter

Sharing some of the findings from a study of fans tweeting as characters from US TV drama The West Wing (NBC, 2000–2006), this article uses data from Twitter observation and fan interviews to examine how participants negotiated the structures of Twitter through this activity. In particular, we consider what implications that negotiation has for the resulting fan text; for how participants perform fandom through this medium; and for how they perceive the value of their fan practice. Through this investigation, the article demonstrates some of the ways in which Twitter facilitates and constrains articulations of audience engagement.
