Web 2.0 is about people, data, and sharing enabled by new technologies. It emphasizes collaboration, community, and harnessing collective intelligence through platforms like wikis, social networks, blogs and user-generated content. For government, Web 2.0 means moving beyond one-stop portals to embrace mashups, reusable content and services, and treating citizens as collaborators. It involves opening up data and empowering users through feedback mechanisms and participatory policy-making. Early adoption of Web 2.0 could increase government efficiency and productivity through tools that facilitate real-time collaboration and information sharing.
