什么是Web2.0? / 2006-08-23


What is Web 2.0?
As with all things online, the Web 2.0 phenomenon is somewhat amorphous. Semantically, tacking a version number to the Web doesn’t make sense (and few agree on what it means) but practically, “Web 2.0” refers to a recent rebirth of sites that focus on user empowerment and open-source applications online. There is a loose set of criteria that bind these sites together and creates the synonymous language that web mavens like Michael Arrington (TechCrunch), John Battelle (BattelleMedia) and Tim O’Reilly (O’Reilly Network) have adopted. In many ways, these elements can be thought of as the formative definition of Web 2.0:
1.User generated and/or user influenced content
2.Applications that use
the Web (versus the desktop) as a platform, in innovative ways
3.Similar visual design and shared functional languages
4.Leveraging of popular trends, including blogging, social tagging, wikis, and peer-to-peer sharing
5.Inclusion of emerging web technologies like RSS, AJAX, APIs (and accompanying mashups), Ruby on Rails and others
6.Open source or sharable/editable frameworks in the form of user-oriented “create your own” APIs

web2.0和web1.0有什么区别?
Web 2.0 Conference网 站的横幅引用Jeff Bezos的话说“Web 1.0 is making the internet for people,web 2.0 is making the internet better for computers”。个人的理解就是web1.0是以门户网站为主导的进行信息发布和传播的一种模式,而web2.0则是以blogger为主导的一种 进行信息发布传播的模式,web2.0更强调网友的这种参与。
