Web 2.0
The term "Web 2.0" describes the changing trends in the use of World Wide Web technology and web design that aim to enhance creativity, communications, secure information sharing, collaboration and functionality of the web. Web 2.0 concepts have led to the development and evolution of web-culture communities and hosted services, 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. ”
Definition
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.
WEB 3.0
What is web 3.0
According to Wikipedia, web 3.0 is only in the speculative stage as the technology is not feasible yet. So what is it?
It was John Markoff of the New York Times who coined the term “web 3. 0” who used it to describe the growing intelligence of the internet and that in the future we will have an “intelligent web” that includes artificial intelligence or AI, microformat which uses old html tags, semantic web which is the use of humans and machines to gather, obtain, share information, data mining and natural language search programs.
Nova Spivak also defined web 3. 0 but he defined it as the 3rd generation of web technology which matures with each new generation. He defined the concepts of the Web 3.0 below:
transformation of the Web from a network of separately siloed applications and content repositories to a more seamless and interoperable whole.
ubiquitous connectivity, broadband adoption, mobile Internet access and mobile devices;
network computing, software-as-a-service business models,
open technologies,
open identity, OpenID,
the intelligent web, distributed databases,
intelligent applications
But after my reading it seems that web 3.0 is gearing toward becoming a 3-D net based on the technology of the game Second Life in which we use avatars to navigate out way through the internet to find what we want and to connect through those 3-D spaces.
As the technology and formats are still far away as we are only now beginning to define Web. 2.0, that I look forward to seeing Web 3.0 and being able to surf cyberspace on an avatar, direct connection with others in a 3-D internet setting, and being able to recyle html to send information is quite
interesting.
Web 3.0 will be a totally new concept where instead of browsing over the net, we will use our avatars in a sim city or 2nd life graphic 3D environment where we view the internet and cyberspace in a 3D world and interact with it directly.
