The analysis of the economic implications of "Web 2.0" applications and loosely-associated technologies such as wikis, blogs, social-networking, open-source, open-content, file-sharing, peer-production, etc. has also gained scientific attention. This area of research investigates the implications Web 2.0 has for an economy and the principles underlying the economy of Web 2.0.
Cass Sunstein's book "Infotopia" discussed the Hayekian nature of collaborative production, characterized by decentralized decision-making, directed by (often non-monetary) prices rather than central planners in business or government.
Don Tapscott and Anthony D. Williams argue in their book Wikinomics: How Mass Collaboration Changes Everything (2006) that the economy of "the new web" depends on mass collaboration. Tapscott and Williams regard it as important for new media companies to find ways of how to make profit with the help of Web 2.0. The prospective Internet-based economy that they term "Wikinomics" would depend on the principles of openness, peering, sharing, and acting globally. They identify seven Web 2.0 business-models (peer pioneers, ideagoras, prosumers, new Alexandrians, platforms for participation, global plantfloor, wiki workplace).
Organizations could make use of these principles and models in order to prosper with the help of Web 2.0-like applications: "Companies can design and assemble products with their customers, and in some cases customers can do the majority of the value creation". "In each instance the traditionally passive buyers of editorial and advertising take active, participatory roles in value creation." Tapscott and Williams suggest business strategies as "models where masses of consumers, employees, suppliers, business partners, and even competitors cocreate value in the absence of direct managerial control". Tapscott and Williams see the outcome as an economic democracy.
Some other views in the scientific debate agree with Tapscott and Williams that value-creation increasingly depends on harnessing open source/content, networking, sharing, and peering, but disagree that this will result in an economic democracy, predicting a subtle form and deepening of exploitation, in which Internet-based global outsourcing reduces labor-costs by transferring jobs from workers in wealthy nations to workers in poor nations. In such a view, the economic implications of a new web might include on the one hand the emergence of new business-models based on global outsourcing, whereas on the other hand non-commercial online platforms could undermine profit-making and anticipate a co-operative economy. For example, Tiziana Terranova speaks of "free labor" (performed without payment) in the case where prosumers produce surplus value in the circulation-sphere of the cultural industries.
Some examples of Web 2.0 business models that attempt to generate revenues in online shopping and online marketplaces are referred to as social commerce and social shopping. Social commerce involves user-generated marketplaces where individuals can set up online shops and link their shops in a networked marketplace, drawing on concepts of electronic commerce and social networking. Social shopping involves customers interacting with each other while shopping, typically online, and often in a social network environment. This involvement of customers in a collaborative business model is also known as customer involvement management (CIM). Academic research on the economic value implications of social commerce and having sellers in online marketplaces link to each others' shops has been conducted by researchers in the business school at Columbia University.

Web APIs
Machine-based interaction, a common feature of Web 2.0 sites, uses two main approaches to Web APIs, which allow web-based access to data and functions: REST and SOAP.
1. REST (Representational State Transfer) Web APIs use HTTP alone to interact, with XML (eXtensible Markup Language) or JSON payloads;
2. SOAP involves POSTing more elaborate XML messages and requests to a server that may contain quite complex, but pre-defined, instructions for the server to follow.
Often servers use proprietary APIs, but standard APIs (for example, for posting to a blog or notifying a blog update) have also come into wide use. Most communications through APIs involve XML or JSON payloads.
See also Web Services Description Language (WSDL) (the standard way of publishing a SOAP API) and this list of Web Service specifications.
XML and RSS
Advocates of "Web 2.0" may regard syndication of site content as a Web 2.0 feature, involving as it does standardized protocols, which permit end-users to make use of a site's data in another context (such as another website, a browser plugin, or a separate desktop application). Protocols which permit syndication include RSS (Really Simple Syndication — also known as "web syndication"), RDF (as in RSS 1.1), and Atom, all of them XML-based formats. Observers have started to refer to these technologies as "Web feed" as the usability of Web 2.0 evolves and the more user-friendly Feeds icon supplants the RSS icon.
Specialized protocols
Specialized protocols such as FOAF and XFN (both for social networking) extend the functionality of sites or permit end-users to interact without centralized websites.

Web-based applications and desktops
Ajax has prompted the development of websites that mimic desktop applications, such as word processing, the spreadsheet, and slide-show presentation. WYSIWYG wiki sites replicate many features of PC authoring applications. Still other sites perform collaboration and project management functions. In 2006 Google, Inc. acquired one of the best-known sites of this broad class, Writely.
Several browser-based "operating systems" have emerged, including EyeOS and YouOS. Although coined as such, many of these services function less like a traditional operating system and more as an application platform. They mimic the user experience of desktop operating-systems, offering features and applications similar to a PC environment, as well as the added ability of being able to run within any modern browser.
Numerous web-based application services appeared during the dot-com bubble of 1997–2001 and then vanished, having failed to gain a critical mass of customers. In 2005, WebEx acquired one of the better-known of these, Intranets.com, for USD45 million.
Another example of a web-based service that didn't survive the dot-com bubble burst was Pets.com. Pets.com business model was flawed in that the products they were selling and delivering to customers' doorsteps had very thin margins and were expensive to ship.

Usage (Web 2.0)
Government 2.0
Web 2.0 initiatives are being employed within the public sector, giving more currency to the term Government 2.0. For instance, Web 2.0 websites such as Twitter, YouTube and Facebook have helped in providing a feasible way for citizens to connect with higher government officials, which was otherwise nearly impossible. Direct interaction of higher government authorities with citizens is replacing the age-old 'single-sided communication' with evolved and more liberal public interaction methodologies.
Higher education
Universities are using Web 2.0 in order to reach out and engage with Generation Y and other prospective students according to recent reports. Examples of this are: social networking websites – YouTube, MySpace, Facebook, Youmeo, Twitter and Flickr; upgrading institutions’ websites in Generation Y-friendly ways (e.g., stand-alone micro-websites with minimal navigation); and virtual learning environments such as Moodle enable prospective students to log on and ask questions. 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.
Public diplomacy
Web 2.0 initiatives have been employed in public diplomacy for the Israeli government. The country is believed to be the first to have its own official blog, MySpace page, YouTube channel, Facebook page and a political blog. The Israeli Ministry of Foreign Affairs started the country's video blog as well as its political blog. The Foreign Ministry also held a microblogging press conference via Twitter about its war with Hamas, with Consul David Saranga answering live questions from a worldwide public in common text-messaging abbreviations. The questions and answers were later posted on Israelpolitik.org, the country's official political blog.

Technology Overview
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. Andrew McAfee used the acronym SLATES to refer to them:
Search
the ease of finding information through keyword search which makes the platform valuable.
Links
guides to important pieces of information. The best pages are the most frequently linked to.
Authoring
the ability to create constantly updating content over a platform that is shifted from being the creation of a few to being the constantly updated, interlinked work. In wikis, the content is iterative in the sense that the people 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 that are simple, one-word descriptions to facilitate searching and avoid rigid, pre-made categories.
Extensions
automation of some of the work and pattern matching by using algorithms e.g. amazon.com recommendations.
Signals
the use of RSS (Really Simple Syndication) technology to notify users with any changes of the content by sending e-mails to them.

The Definition of Web 2.0
Definition
From Wikipedia, the free encyclopedia
Web 2.0 encapsulates the idea of the proliferation of interconnectivity and interactivity of web-delivered content. Tim O'Reilly regards Web 2.0 as the way that business embraces the strengths of the web and uses it as a platform. 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, as opposed to expecting the Internet to suit as a platform (effectively "fighting the Internet").
In the opening talk of the 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.
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-3 applications, the most "Web 2.0"-oriented, exist only 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. O'Reilly gave eBay, Craigslist, Wikipedia, del.icio.us, Skype, dodgeball, and AdSense as examples.
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", like Google Earth). In addition, Gmail.

TENTANG WEB 2.0...(English version)
Web 2.0
(From Wikipedia, the free encyclopedia)
It has been suggested that Web 1.0 be merged into this article or section. A tag cloud presenting Web 2.0 themes.
The term "Web 2.0" refers to a perceived second generation of web development and design, that aims to facilitate communication, secure information sharing, interoperability, and collaboration on the World Wide Web. Web 2.0 concepts have led to the development and evolution of web-based communities, hosted services, and applications; such as social-networking sites, video-sharing sites, wikis, blogs, and folksonomies.
The term first became notable after the O'Reilly Media Web 2.0 conference in 2004. Although the term suggests a new version of the World Wide Web, it does not refer to an update to any technical specifications, but rather to changes in the ways software developers and end-users utilize the Web. According to Tim O'Reilly:
“Web 2.0 is the business revolution in the computer industry caused by the move to the Internet as a platform, and an attempt to understand the rules for success on that new platform.”
O'Reilly has said that the "2.0" refers to the historical context of web businesses "coming back" after the 2001 collapse of the dot-com bubble, in addition to the distinguishing characteristics of the projects that survived the bust or thrived thereafter.
Tim Berners-Lee, inventor of the World Wide Web, has questioned whether one can use the term in any meaningful way, since many of the technological components of Web 2.0 have existed since the early days of the Web.
