Characteristics:
Web 2.0 Web 2.0 websites allow users to do more than just retrieve information.
They can build on the interactive facilities of "Web 1.0" to provide "Network as
platform" computing, allowing users to run software-applications entirely through a browser.
A Web 2.0 website must include:
1. CSS
2. Folksonomies (collaborative tagging, social classification, social indexing, and
social tagging)
3. Microformats extending pages with additional semantics
4. REST and/or XML- and/or JSON-based APIs
5. Rich Internet application techniques, often Ajax-based
6. Semantically valid XHTML and HTML markup
7. Syndication, aggregation and notification of data in RSS or Atom feeds
8. mashups, merging content from different sources, client- and server-side
9. Weblog-publishing tools
10. wiki or forum software, etc., to support user-generated content
11. Internet privacy, the extended power of users to manage their own privacy in
cloaking or deleting their own user content or profiles.
Associated innovations:
It is a common misconception that "Web 2.0" refers to various visual design elements
such as rounded corners or drop shadows. While such design elements have commonly been found on popular Web 2.0 sites, the truth is that the association is merely one of fashion,a designer preference which became popular around the same time that "Web 2.0" became a buzz word.
