Nowadays, the government is searching for new ideas to improve public governance so that it is not only more cost-effective in service delivery but also more responsive to the needs of multiple stakeholders including the citizens, political authorities, and administrative bodies. The Web technologies and applications have entered the phase of the conceptual umbrella of Web 2.0, which has been drawing increasing attention from public agencies. It is argued that Web 2.0 applications such as blogs, wikis, web syndication or web feeds, and a number of social networking services are useful tools for enhancing interactive collaboration and public participation. Web 2.0 can facilitate better service delivery by offering a platform where the government officials can exchange information more efficiently. Web 2.0 may as well help establish citizen-centric initiatives that reflect the core values of public services such as responsiveness, transparency, and social inclusiveness. In turn, this paper empirically examines the proposition that Web 2.0 enhances citizen participation. The literature suggests that the adoption and diffusion of technology-based initiative is subject to bureaucrat attitude. The purpose of this paper aims to explore government officials' perception and intention to adopt Web 2.0-based citizen participation initiatives. The research model integrates the concepts of Technology Acceptance Model (TAM). A questionnaire is used to measure government officials' intention to adopt Web 2.0 in eGovernment. Structural Equation Modeling (SEM) is used to further analyze the data and to design a theoretical model delineating the effects of perceived ease of use, perceived usefulness of e-services, attitude and trust. As the government is paying increasing attention to what Web 2.0 has to offer in public governance, this paper proposes a synthetic model in a timely manner to understand government officials' intention as well as perceived obstacles to adopt Web 2.0 in participatory eGovernment initiatives.
