INTRODUCTIONInformation behaviour is a term used to describe various ways in which people interact with information and utilise it (Bates, 2005). Information behaviour refers to human behaviour in relation to information, and explicit, implicit and tacit mental states related to information. The information behaviour literature identifies several discrete information behaviours, such as recognition of information needs (Belkin, 2008), information seeking (Chatman, 1991), information use (Bartlett & Toms, 2005), berry-picking (Bates, 1990), and information foraging (Pirolli & Card, 1999). Much of information behaviour research has focused on individuals' day-to-day information needs rather than information behaviours for professional purposes in online space. In information age, use of microblogs has significantly transformed way people seek and use information (Power, 2015). The microblogging phenomenon has also influenced information behaviours, but this influence has not yet been considered in relation to existing information behaviour models. In digital age, professionals use information that is available on Internet creatively, and share it as posts on social media. The audience who can access and read these posts are much wider than audience of traditional word-of-mouth information sharing or dissemination (Hughes, Rowe, Batey, & Lee, 2012). However, not all professionals use social media in same way. Social media relationships differ between strong-ties and weak-ties type users. Strong-ties type users consider their online social networks to be as real and interactive as their offline interactions; for weak-ties users, the online network can be something qualitatively different, where privacy is virtually non-existent (Skageby, 2012, p. 332). In both cases, their networks are carefully selected. In weak-ties framework, an individual's network comprises weak-ties (acquaintances) and strong-ties (close family and friends). One advantage of weak-ties framework is that weak-ties are more useful sources of new information, because individuals with strong-ties usually possess same information as other members of network. Hence, weak-ties type users have a wider network, but not much personal interaction or participation in that network. Skageby (2012) has conducted ethnographic studies of Facebook, Flickr and a music-sharing site; however, users examined in that study were not part of a professional network. It would be useful to explore, as this current study does, whether information technology (IT) professionals, who can be assumed to be more familiar with privacy and security implications of social media, have similar perceptions when using Twitter.The literature confirms that online spaces enable online collaboration, facilitate social interaction and attract wider audiences as well as participants worldwide. Microblogs support online collaboration that is independent of time and place (Ebner, Lienhardt, Rohs, & Meyer, 2010). This is because microblogs are perceived as places, comparable to physical spaces, that engender a sense of belonging that enable IT professionals to create communities of practice. This is consistent with extant research findings that Twitter is a flexible and powerful electronic form of word-of-mouth communication channel for sharing and disseminating information (Jansen, Zhang, Sobel, & Chowdury, 2009). It allows users to repurpose tool to suit their needs (Straumsheim, 2014). The flexibility and usability of Twitter encourage IT professionals to use it for professional purposes. Twitter has helped IT professionals to share their knowledge and create communities of practice much more easily compared to offline information grounds. An information ground refers to a public (and physical) social setting where people go to carry out everyday life activities such as eating and hairdressing, but ultimately end up engaging in seeking and sharing of information (Fisher, Landry, & Naumer, 2007). …
