A marketing term to differentiate new web businesses from those of the dot com boom, which due to the bust now seem discredited

"Web 2.0" refers to what some people see as a second phase of development of the World Wide Web, including its architecture and its applications.

The syndication and messaging capabilities found in Web 2.0 suggest the potential to create a more tightly-woven social fabric among disparate online communities. While terms have been invented to treat these communities collectively, including blogosphere for the world of weblogs, syndisphere for content syndication feeds, and wikisphere for wikis, other observers consider the wording and the implied value to be excessive.

Web 2.0, a phrase coined by O'Reilly Media in 2004[1], refers to a supposed second generation of Internet-based services—such as social networking sites, wikis, communication tools, and folksonomies—that emphasize online collaboration and sharing among users.

Tim O'Reilly and John Battelle summarized key principles they believed characterized Web 2.0 applications: the Web as a platform data as the driving force network effects created by an architecture of participation innovation in assembly of systems and sites composed by pulling together features from distributed, independent developers (a kind of "open source" development) lightweight business models enabled by content and service syndication the end of the software adoption cycle ("the perpetual beta") software above the level of a single device, leveraging the power of The Long Tail.

As used by its proponents, the phrase "Web 2.0" refers to one or more of the following: The transition of web-sites from isolated information silos to sources of content and functionality, thus becoming computing platforms serving web applications to end-users A social phenomenon embracing an approach to generating and distributing Web content itself, characterized by open communication, decentralization of authority, freedom to share and re-use, and "the market as a conversation" A more organized and categorized content, with a far more developed deeplinking web architecture than hithertofore A shift in economic value of the Web, possibly surpassing that of the dot com boom of the late 1990s A marketing-term used to differentiate new web-based firms from those of the dot-com boom, which (due to the bust) subsequently appeared discredited The resurgence of excitement around the implications of innovative web-applications and services that gained a lot of momentum[citation needed] around mid-2005

Web 2.0, a phrase coined by O'Reilly Media in 2004,^[1] refers to a perceived second-generation of Web-based services—such as social networking sites, wikis, communication tools, and folksonomies—that emphasize online collaboration and sharing among users. O'Reilly Media used the phrase as a title for a series of conferences, and it has since become widely adopted.

Though the term suggests a new version of the Web, it does not refer to an update to Internet or World Wide Web technical standards, but to changes in the ways those standards are used. According to 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."^[2].

Some technology experts, notably Tim Berners-Lee, have questioned whether the term is meaningful, since many of the technology components of "Web 2.0" have been present since the creation of the World Wide Web

In the opening talk of a first Web 2.0 conference, O'Reilly and John Battelle summarized what they saw as the themes of Web 2.0. 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. (This could be seen as a kind of "open source" or possible "Agile" development process, consistent with an end to the traditional software adoption cycle, typified by 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.^[7]

O'Reilly provided examples of companies or products that embody these principles in his description of his four levels in the hierarchy of Web 2.0 sites:

Level-2 applications can operate offline but gain advantages from going online. O'Reilly cited Flickr, which benefits from its shared photo-database and from its community-generated tag database.

Level-1 applications operate offline but gain features online. O'Reilly pointed to Writely (now Google Docs & Spreadsheets) and iTunes (because of its music-store portion).

Level-0 applications work as well offline as online. O'Reilly gave the examples of MapQuest, Yahoo! Local, and Google Maps (mapping-applications using contributions from users to advantage could rank as "level 2").

The key here is that these technologies are collaborative in nature and focus on user-created material.

The Web we know now, which loads into a browser window in essentially static screenfuls, is only an embryo of the Web to come. The first glimmerings of Web 2.0 are beginning to appear, and we are just starting to see how that embryo might develop The Web will be understood not as screenfuls of text and graphics but as a transport mechanism, the ether through which interactivity happens. It will [...] appear on your computer screen, [...] on your TV set [...] your car dashboard [...] your cell phone [...] hand-held game machines [...] and maybe even

…the network as platform, spanning all connected devices; Web 2.0 applications are those that make the most of the intrinsic advantages of that platform: delivering software as a continually-updated service that gets better the more people use it, consuming and remixing data from multiple sources, including individual users, while providing their own data and services in a form that allows remixing by others, creating network effects through an "architecture of participation," and going beyond the page metaphor of Web 1.0 to deliver rich user experience.”^[12]

Web 2.0 websites typically include some of the following features/techniques. Andrew McAfee used the acronym SLATES to refer to them:^[19]

Search: The ease of finding information through keyword search.
Links: Ad-hoc guides to other relevant information.
Authoring: The ability to create constantly updating content over a platform that is shifted from being the creation of a few to being constantly updated, interlinked work. In wikis, the content is iterative in the sense that users undo and redo each other's work. In blogs, content is cumulative in that posts and comments of individuals are accumulated over time.
Tags: Categorization of content by creating tags: simple, one-word user-determined descriptions to facilitate searching and avoid rigid, pre-made categories.
Extensions: Powerful algorithms that leverage the Web as an application platform as well as a document server.
Signals: The use of RSS technology to rapidly notify users of content changes.

The concept of Web-as-participation-platform captures many of these characteristics. Bart Decrem, a founder and former CEO of Flock, calls Web 2.0 the "participatory Web"^[9] and regards the Web-as-information-source as Web 1.0.

The impossibility of excluding group-members who don’t contribute to the provision of goods from sharing profits gives rise to the possibility that rational members will prefer to withhold their contribution of effort and free-ride on the contribution of others.^[10] According to Best,^[11] the characteristics of Web 2.0 are: rich user experience, user participation, dynamic content, metadata, web standards and scalability.

Universities are using Web 2.0 in order to reach out and engage with generation ผี and other prospective students according to recent reports.^[16] Examples of this are: social networking websites – YouTube, MySpace, Facebook, Youmeo, Twitter and Flickr; upgrading institutions’ websites in gen Y-friendly ways – stand-alone micro-websites with minimal navigation; placing current students in cyberspace^{[clarification needed]} or student blogs; and virtual learning environments such as Moodle enable prospective students to log on and ask questions.^{[clarification needed]}

In addition to free social networking websites, schools have contracted with companies that provide many of the same services as MySpace and Facebook, but can integrate with their existing database. Companies such as Harris Connect, iModules and Publishing Concepts have developed alumni online community software packages that provide schools with a way to communicate to their alumni and allow alumni to communicate with each other in a safe, secure environment.

Adobe Flash is another technology often used in Web 2.0 applications. As a widely available plugin independent of W3C (World Web Consortium, the governing body of web standards and protocols), standards, Flash is capable of doing many things which are not currently possible in HTML, the language used to construct web pages. Of Flash's many capabilities, the most commonly used in Web 2.0 is its ability to play audio and video files. This fact alone has allowed for the creation of cutting edge Web 2.0 sites such as YouTube, where rich media is gracefully integrated with standard HTML.
