Here, we introduce TwitterHitter, an application that leverages GIScience and information visualization techniques to harvest spatiotemporal insights from microblogging generally and Twitter.com specifically. Microblogging describes a one-to-many form of computer-mediated communication that allows individuals or organizations to broadcast brief messages about their status, interests, and opinions via the web (Grace, Zhao, and Boyd 2010). Microblogging is a faster method of information sharing than traditional blogging, leading to more frequent updates, and is a broader method of communication than text messaging or email, leading to updates containing content intended for public viewing (Starbird et al. 2010). Microblogging offers informative and timely information that may be useful in a variety of application domains, including emergency response (Longueville, Smith, and Luraschi 2009; Starbird and Palen 2010), epidemiology and public health (Brownstein, Freifeld, and Madoff 2009; Scanfeld, Scanfeld, and Larson 2010), mobile education (Ebner and Schiefner 2008), news monitoring and recommendation (Grinev et al. 2009; Phelan, McCarthy, and Smyth 2009), and workplace coordination/collaboration (Zhao and Rosson 2009; Zhang et al. 2010).
