“Web 2.0” is commonly associated with web development and web design that facilitates interactive information sharing, interoperability, user-centered design and collaboration on the World Wide Web. Examples of Web 2.0 include web-based communities, hosted services, web applications, social-networking sites, video-sharing sites, wikis, blogs, mashups and folksonomies. A Web 2.0 site allows its users to interact with other users or to change website content, in contrast to non-interactive websites where users are limited to the passive viewing of information that is provided to them.

Technology overview

Web 2.0 draws together the capabilities of client– and server-side software, content syndication and the use of network protocols. Standards-oriented web browsers may use plugins and software extensions to handle the content and the user interactions. Web 2.0 sites provide users with information storage, creation, and dissemination capabilities that were not possible in the environment now known as “Web 1.0”.

Web 2.0 websites typically include some of the following features and techniques. Andrew McAfee used the acronym SLATES to refer to them:

Search

Finding information through keyword search.
Links
Guides to other related information.
Authoring
The ability to create and update content leads to the collaborative work of many rather than just a few web authors. In wikis, users may extend, undo and redo each other’s work. In blogs, posts and the comments of individuals build up over time.
Tags
Categorization of content by users adding one-word descriptions to facilitate searching, without dependence on pre-made categories.
Extensions
Software that makes the Web an application platform as well as a document server.
Signals
The use of syndication technology such as RSS to notify users of content changes.
