The introduction of the Internet in the 1990s, including near-instant messaging (email) solutions, instant messaging (IM) solutions, and the World Wide Web , has changed the nature of both commercial and social interactions. The invention of Web 2.0 technology (McAfee 2006), which enables a two-way method of communication, interoperability, and user-generated content (UGC), has enabled businesses to create virtual communities and a collaborative environment to host web-based communities as a foundation for value creation. Social networking sites (SNS), such as Facebook, Google+, and Twitter, are just a few examples; such sites offer space for both improved collaboration and a large amount of user-generated content (Kaplan & Haenlein 2010), which allows the user to become the true owner of data and information. “Social networks in the workplace provide employees with new ways to interact with their colleagues and offer a platform for sharing information” (Leftheriotis & Giannakos 2014, p.). Email has become an important tool for all business communications; and based on research, a significant amount of employee time is spent organizing and managing emails. Due to the increasing use of email in the workplace, a significant amount of company knowledge is stored within individual email accounts and inboxes that are not easily shareable and accessible to other employees. This is an expected outcome, as employees are paid to produce rather than browse information (McAfee 2006), so they use channels and means that allow them to generate new information, such as email. Research conducted by Davenport on corporate email users shows that 100% of knowledge workers use email as a communication channel, in comparison...... middle of paper ......vis, Bagozzi et al. 1989, p. ), assuming that the successful implementation of ESN systems depends on two factors: initial acceptance and continued use. We are using the information systems (IS) success model, as proposed by DeLone (1988) and DeLone and McLean (2003), as a general and basic theoretical model for measuring IS system success, i.e. ENS; and we are specifically measuring factors that impact acceptance of that technology and continued use. We are using current technology acceptance models, e.g. (TAM) (Davis 1989), and factors affecting the continued use of technology, e.g. technology continuation theory (TCT) (Liao, Palvia et al. 2009 ), as well as other relevant theories to evaluate and identify a construct that can be used by businesses to accelerate the initial adoption, acceptance and continued use of that technology
