The document discusses several emerging technologies including del.icio.us, wikis, blogs, podcasts, and the evolution of the World Wide Web from Web 1.0 to Web 2.0 to Web 3.0 (proposed Web 3.0). Del.icio.us is described as a social bookmarking service that allows flexible organization of bookmarks using tags. Wikis are defined as collaborative websites that allow users to edit pages. Blogs, podcasts, and their key features are also summarized. The differences between Web 1.0, 2.0, and the vision for Web 3.0 are outlined at a high level.

12. Essential Characteristics The one that has most strikingly set wikis apart from other web based forums and discussions is that of multiple contributors. Unlike a blog, for example, which has one main identifiable author, a wiki web page may be authored and edited by a number of people. Not only may an individual contributor edit their own work, but also edit the work of others. Some speak of wiki pages in their purest form as never being finished and always in the process of being edited and expanded.

13. Uses Collaborating on business ideas with team across geographies Business Wikis are being used for Project Management, mission statement and cross-company collaborations Fosters trust between groups due to openness Wikibooks for collaborative nonfiction, recepies, wikimedia for citizen journalists.

Online guestbooks, GIF buttons HTML forms sent via email . Web 2.0: Web 2.0 encapsulates the idea of the proliferation of interconnectivity and interactivity of web-delivered content. Level-3 applications , the most &quot;Web 2.0&quot;-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.

46. Web 1.0, 2.0 and 3.0 Web 2.0: Technology Overview 1. Search: the ease of finding information through keyword search which makes the platform valuable. 2. Links: guides to important pieces of information. The best pages are the most frequently linked to. 3. 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. 4. Tags: categorization of content by creating tags that are simple, one-word descriptions to facilitate searching and avoid rigid, pre-made categories. 5. Extensions: automation of some of the work and pattern matching by using algorithms e.g. amazon.com recommendations. 6. Signals: the use of RSS (Really Simple Syndication) technology to notify users with any changes of the content by sending e-mails to them.
