IntroductionSocial media have changed the nature of communication - whether peer-to-peer, business to consumer or business-to-business. Social networking sites such as Facebook and micro-blogging sites, for example, Twitter, have become some of the primary sources of communication for people to communicate with others in their network and about brands with which they identify (Bright et al., 2015). This is worldwide phenomenon and there are many definitions of social media, many of which have come from bloggers and pundits - selfdescribed experts in the field. Managers have struggled with not just how to benefit from social media strategies, but even how to classify social media in way that is meaningful to their goals to their goals. Kaplan and Haenlein (2010) define these as a group of Internetbased applications that build on the ideological and technological foundations of Web 2.0 and that allow the creation and exchange of user-generated content. Dabbagh and Reo consider social media to be variety of networked tools or technologies that emphasise the social aspects of the Internet as channel for communication, collaboration and creative expression (Stefko et al., 2014; Dabbagh & Reo, 2011a). In order to understand the aim and nature of social media it is necessary to focus on specific examples. Social media include experienceand resource-sharing tools such as Delicious, WordPress and Twitter that enable online/social bookmarking, blogging, and microblogging; there is wiki software such as PBworks that enables the creation of collaborative workspaces; media sharing tools such as Flickr and YouTube that enable social tagging; social networking sites (SNS) such as Facebook and LinkedIn that enable social networking as well as web-based (cloud-computing) office tools such as Google Apps that enable document and calendar sharing and editing, amongst other features (Dabbagh & Reo, 2011b; Kitsantas & Dabbagh, 2010). While social media are now changing the way people obtain and share information, the concept of this means of communication has not been clearly defined, but is related to its decentralised nature. People can use it to create and share information, as well as to obtain feedback (Chiabai et al., 2014; Moran et al., 2011). However, there are also certain concerns. The use of new media and technology has been portrayed in negative manner, with adults and media identifying social media as reason for the declining morality of today's youth (Thurlow, 2006).1. Literature reviewSocial media usage rates continue to rise; the amount of time spent on social media and the amount of content encountered on them The increase in the rates of social media usage can perhaps be gauged in that the amount of time spent on social media and the amount of content encountered on social media seem to be triggers for social media fatigue.. For example, social networking accounts for 22% of all of the time spent online in the U.S. and global consumers spend an average of more than 6 h per week on social networking sites (Nielsen, 2011). The ubiquity of social media is phenomenon that does not seem to be diminishing, but is in fact still on the rise, with usage of up to 800% more than in 2005 (Olenski, 2013). Seventy-two percent (72%) of adults use social media sites with about 1.1 billion people using the Facebook social media site alone: that is about one out of every seven people on the planet, and these statistics are for just one social media site (Olenski, 2013). Social media is trending topic at the moment, having received much mass media and consumer attention for its widespread adoption during the last decade. Social media have influenced practice in many communication-oriented fields, such as marketing, customer service and journalism. In education, the publicity surrounding social media has created great deal of speculation about how it might be used in higher education environment. …
