Top1. Introduction
It is becoming well known by researchers that the emergence of Web 2.0 tools and applications is considered the next generation of inter-personal communications (London, 2007). Some of the widely used Web 2.0 technologies by popular web sites included Blogs, Wikis, Social Networking sites, and File Sharing (Davis, 2009; Sankar et al., 2009). Through social media dialogue and user-generated content including social networking sites, Web 2.0 encourages interaction and collaboration i.e., web applications, folksonomies, mashups, video sharing, instant messaging (IM), and hosted services (Franchi et al., 2013; Lellinger, 2010; Monticolo et al., 2011; Shuen, 2008). Therefore, it is not surprising that Web 2.0 caused fundamental changes to online technologies and electronic commerce (Jordan-Meier, 2011; Randazza, 2009).
What is unique about Web 2.0 is that all information is available (shareable, social) through simple, ubiquitous and functional web sites. Web 2.0 capitalizes on two main features, Web-based information sharing and voice and messaging features (Bonnin, 2009). Web-based information sharing is associated with using blogs, wikis, social networking and collaborative content portals, and syndicated feeds (Bonnin, 2009; Monticolo et al., 2011). Wikis, for example, allow users to access multiple information and other contents and edit them online. Examples include Wikipedia, Flickr, and MySpace. Wikis are operated by 6% of IT based companies and used by about 25% of the company employees (Bonnin, 2009; Monticolo et al., 2011; Simha, et al., 2009). Voice and messaging allows Web 2.0 connect people in various ways that are associated with certain specifications such as blending of voice, video, messages, and click-to-call functionality including Voice over IP (VOIP), instant messaging (IM), unified communications, and video conferencing (Dwivedi, 2008). Several Web-based services and applications are included in Web 2.0. Web 2.0 services are based on four wide types of technologies (Publication, Syndication, Collaboration, and Recombination) (Rudman, 2010).
