過去十年來，政府所扮演直接服務的角色已逐漸由提供規制和治理的私人和非盈利組織所取代。Web 2.0的服務與技術為Tim O'Reilly在2004年所提出，並以驚人的速度傳遍世界廣為世人所用。Web 2.0為網路技術設計應用，其目的在提升使用者的創作力與資訊分享。這股經由網際網路平臺所創造之電腦產業風潮，引領著社會大眾對Web 2.0成功典範進行更進一步的探討。Web 2.0不同於Web 1.0單向傳達資訊內容的模式，它容許更多以服務為導向的互動參與與資訊擴展。伴隨著日益成長的風潮，愈來愈多的證據顯示出，Web 2.0確可憑藉其所能產出的社會導正面向、服務公眾利益、公共價值的共同創造與加強政府的課責性與透明度等能力，幫助公共組織展現出高效能的服務。例如部落格Blogs、維基wikis、聊天室chat rooms、播客podcasts、簡易資訊聚合RSS和其它的混搭程式mashup應用，都構成現今電子化政府不可或缺的環節。因此，我們可以得出結論就是Web 2.0的應用在今日社會確有其重要性，而且此項發展為公部門所不可忽視。本文將進行探討Web 2.0應用在未來電子化政府發展的意涵；然而，對於實體與虛擬世界交錯盤纏下所帶來新的危機與挑戰，諸如伴隨Web 2.0而來的隔離性、排它性、侵犯隱私及資訊誤用等負面議題也應一併列入考慮。

Over the last decade, the role played by governments has moved further away from direct service provision towards regulation and governance of services provided by a multiplicity of private and non-profit entities. Web 2.0 technologies and services coined by Tim O'Reilly in 2004 have spread around the world at an amazing pace and are used by billions of people every day. Web 2.0 is in the use of the web technology and design that aims to facilitate creativity, information sharing, and collaboration among users. This computer industry revolution was caused by the move to the Internet as a platform, and an attempt to understand the success on that new paradigm. Unlike the basic publication, access, and content delivery model of Web 1.0, Web 2.0 promises to be more interactive, participatory, content rich, seamless, scalable, and service oriented. With the growing interest in Web 2.0 trends, more evidences shows that Web 2.0 helps public service organizations deliver high performance in terms of their ability to generate positive social outcomes, to serve the common good, to engage the public co-producers of public value and to improve accountability and transparency. Blogs, wikis, chat rooms, podcasts, Really Simple Syndication (RSS) and other mashup applications are all part of this process being adopted by some e-Government sites. Consequently, we can conclude that Web 2.0 applications gain in importance in today's society and this development cannot be ignored by the public sector. In this paper we explore the implications of Web 2.0 applications on the further development of e-Government; nevertheless, the interweaving of the physical and virtual world brings news risks and challenges, it should to take into account the potential negative issues like isolation, exclusion, violation of privacy and misuse of information of Web 2.0 avatar as well.
