"Web 2.0 is a knowledge-oriented environment where human interactions generate content that is published, managed and used through network applications in a service-oriented architecture."
Eric Schmidt (CEO Google, Seoul Digital Forum, May 29 - 31 2007)
Mature Web 2.0 (in fact he said "3.0", identifying 2.0 with AJAX) ... "will ultimately be seen as applications that are pieced together. They are relatively small, the data is in the cloud, the applications can run on any device, PC or mobile phone, the applications are very fast and they are very customizable. They will be distributed virally ... That's a very different application model than we'd ever seen in computing ..."
Tim O'Reilly:
"Web 2.0 is the business revolution in the computer industry caused by the move to the Internet as platform, and an attempt to understand the rules for success on that new platform." -- many of the technology components of "Web 2.0" have existed since the early days of the Web.
O'Reilly considers that Eric Schmidt's abridged slogan, don't fight the Internet, encompasses the essence of Web 2.0 — building applications and services around the unique features of the Internet. ...
They argued that the web had become a platform, with software above the level of a single device, leveraging the power of the "Long Tail", and with data as a driving force. According to O'Reilly and Battelle, an architecture of participation where users can contribute website content creates network effects. Web 2.0 technologies tend to foster innovation in the assembly of systems and sites
composed by pulling together features from distributed, independent
developers (a kind of "open source" development and an end to the
software-adoption cycle (the so-called "perpetual beta"). Web 2.0 technology encourages lightweight business models enabled by syndication of content and of service and by ease of picking-up by early adopters.
Level-3 applications, the most "Web 2.0"-oriented, only exist on the
Internet, deriving their effectiveness from the inter-human connections
and from the network effects that Web 2.0 makes possible, and growing
in effectiveness in proportion as people make more use of them.
"...all those Internet utilities and services sustained in a data base
which can be modified by users whether in its content (adding, changing
or deleting- information or associating metadates with the existing
information), or how to display them, or in content and external aspect
simultaneously."
According to Best,
the characteristics of Web 2.0 are: rich user experience, user
participation, dynamic content, metadata, web standards and
scalability. Three further characteristics that Best did not mention
about web 2.0: openness, freedom and collective intelligence by way of user participation – all should be viewed as essential attributes of Web 2.0.

The sometimes complex and continually evolving technology infrastructure of Web 2.0 includes server-software, content-syndication, messaging-protocols, standards-oriented browsers with plugins and extensions, and various client-applications. The differing, yet complementary approaches of such elements provide Web 2.0 sites with information-storage,
creation, and dissemination challenges and capabilities that go beyond
what the public formerly expected in the environment of the so-called
"Web 1.0".
Web 2.0 websites typically include some of the following features/techniques:
- rich Internet application techniques, often Ajax-based
- semantically valid XHTML and HTML markup
- microformats extending pages with additional semantics
- folksonomies (in the form of tags or tagclouds, for example)
- Cascading Style Sheets to aid in the separation of presentation and content
- REST and/or XML- and/or JSON-based APIs
- syndication, aggregation and notification of data in RSS or Atom feeds
- mashups, merging content from different sources, client- and server-side
- weblog-publishing tools
- wiki or forum software, etc., to support user-generated content
