Web 2.0 字串7

Web 2.0 (or Web 2) is the popular term for advanced Internet technology and applications including blogs, wikis, RSS and bookmark sharing. The expression was originally coined by O’Reilly Media and MediaLive International in 2004, following a conference dealing with next-generation Web concepts and issues.

The two major components of Web 2.0 are the technological advances enabled by Ajax and other new applications such as RSS and Eclipse and the user empowerment that they support. One of the most significant differences between Web 2.0 and the traditional World Wide Web (retroactively referred to as Web 1.0) is greater collaboration among Internet users and other users, content providers, and enterprises. Originally, data was posted on Web sites, and users simply viewed or downloaded the content. Increasingly, users have more input into the nature and scope of Web content and in some cases exert real-time control over it. For example, multiple-vendor online book outlets such as BookFinder4U make it possible for users to upload book reviews as well as find rare and out-of-print books at a minimum price, and dynamic encyclopedias such as Wikipedia allow users to create and edit the content of a worldwide information database in multiple languages. Internet forums have become more extensive and led to the proliferation of blogging. The dissemination of news evolved into RSS. There is no clear-cut demarcation between Web 2.0 and Web 1.0 technologies, hardware, and applications. The distinction is, to a large extent, subjective. Here are a few characteristics often noted as descriptive of Web 2.0:

Critics of Web 2.0 maintain that it makes it too easy for the average person to affect online content and that, as a result, the credibility, ethics and even legality of Web content could suffer. Defenders of Web 2.0 point out that these problems have existed ever since the infancy of Web, and that the alternative―― widespread censorship based on ill-defined elitism――would be far worse. The final judgment concerning any Web content, say the defenders, should be made by end users alone, and Web 2.0 reflects evolution in that direction. 字串1

Web 2.0（或Web 2）是一个有关先进的因特网技术和应用的通俗叫法，其中包括博客、wiki、RSS和书签共享。这个说法最初是在 2004年一次有关下一代Web概念和问题的会议之后，由O’Reilly Media 公司和MediaLive International 公司创造的。 字串7

Web 2.0有两大部分：由Ajax实现的技术进步以及诸如RSS和Eclipse的新颖应用和这些新应用支持的用户自我实现。Web 2.0和传统的万维网（可以称之为Web 1.0）之间最主要的区别之一就是因特网用户和其他用户、内容提供商和企业之间更大的协作。最初，数据是被贴到网站，用户只是简单地观看或下载内容。逐步地，用户对Web内容的性质和范围拥有了更多的输入手段、以及在某些情况下能对其实施实时控制。例如，BookFinder4U一类的多商家在线书籍能使用户实现上载书评以及以最低的代价找到稀有的和停止印刷的书籍，像 Wikipedia那样的动态百科全书让用户用多种语言建立和编辑全球范围信息的数据库。因特网论坛已经变得更广泛并导致了博客的扩散。新闻的分发发展成RSS。在Web 2.0和Web 1.0的技术、硬件和应用之间，没有明显的区分。在很大程度上，这种区分是主观的。在描述Web 2.0时常常提到的特性有

Web 2.0的批评者认为，它使普通的人能非常容易地影响在线内容，结果使Web内容的可信度、道德规范、甚至合法性受到影响。而Web 2.0的捍卫者指出这些问题在Web一出现就存在，而替代方法，即广泛的基于精英政治错误定义的审查使问题变得更糟。捍卫者们称，有关Web内容的最终判断应由最终用户单独做出，Web 2.0就是在朝这个方向演变。
