FreeMind is a premier free mind-mapping (http://en.wikipedia.org/wiki/Mind_map) software written in Java. The recent development has hopefully turned it into high productivity tool. We are proud that the operation and navigation of FreeMind is faster than that of MindManager because of one-click "fold / unfold" and "follow link" operations.

Obasanjo writes, "Google is tipping it's search results to favor Knol. Or at least that is the conclusion of several search engine optimization (SEO) experts and also jibes with my experiences." He Danny Sullivan, who writes, "I was surprised to see a post covering how Knol's How to Backpack was already hitting the number three spot on Google. Really? I mean, how many links could this page have gotten already?" Also, Aaron Wall notes that "if Google notices duplicate content then it favors the content on Knol over a site that has existed for years and has decent PageRank."

Si tu essayes de définir le web2 tu vas t’arracher les cheveux… Le principe du schéma est très très bon, car il permet d’exprimer l’inexprimable ! Pour ma part, je pense que le web2 ne se définit pas, tout simplement car on ne définit pas une époque ! Le web2 c’est une époque, une période qui correspond à une mutation des usages grâce à des évolutions techniques. On peut lister les usages, lister les évolutions techniques, essayer de comprendre pourquoi il y a eu une évolution, mais définir un terme à la base “marketing” je ne vois pas l’intérêt. On peut le schématiser, on peut donner des exemples, imaginer ce que sera la suite, mais le définir… impossible, voir absurde ! Ex : wikipedia c’est totalement web2 non ? Pourtant ca existait bien au moment du web1 non ? Alors le web1 était aussi web2 ou c’est l’inverse ? Bref, du débat à perte de vue en perspective… peu constructif… et qui aura comme conséquence l’effet inverser recherché : semer le trouble. Ton schéma est très très bon. Il ne présente pas tous les concepts (et c’est pour ça qu’il est bon). Autant multiplier les schémas autant de fois qu’il y a un concept fondateur du web2. Un exemple de schéma qui serait intéressant, serait de mettre en regard les évolutions technologiques avec les mutations des usages sur une ligne temporelle. Ex : généralisation du haut débit (technique) ->augmentation du tps passé par les internautes sur le net + augmentation de la consommation de médias lourds (photos, vidéos)->Youtube. etc !

What Is Web 2.0? Web 2.0 is the next evolution of the web that has a new usage paradigm as well as a new technology paradigm. The former is characterized by “architecture of participation” and the latter is characterized by “architecture of partition”. The “Consumer-centric” View Causes Confusion There is no doubt that the “web 2.0” phenomenon is ignited by the success of consumer websites like MySpace, YouTube and Flickr.  From these consumer website, analysts established “social networking” via the network effect as a key feature of web 2.0. Though it is possible that enterprise oriented social computing applications may emerge to address specific enterprise concerns, it is not clear how social networking can change enterprise IT on a more fundamental level. Analysts further characterized “Architecture of Participation” as another key element of web 2.0, as evident from YouTube and Flickr. Similarly it is unclear whether/how “architecture of participation” would impact enterprise IT mission. Enterprise IT’s mission is simple: to enable and facilitate the interaction and integration of IT systems and people. There is no doubt that web 2.0 applications like blogs and wikis based on “architecture of participation” can be useful to enterprises, but is there anything beyond blogs and wikis? The key technology behind most consumer web 2.0 websites, Ajax, is not new. The popular “mashup” concept sounds new but in reality is based on what has been built into the browser for many years. The “consumer-centric” perspective limits how we look at the technology aspect of web 2.0 and leads to the conclusion that web 2.0 involves no technology advancement. Further, “architecture of participation”, “social networking” and “harness the collective intelligence” are all usage patterns. They do not relate to technology. In fact, they can be supported well on web 1.0 technologies; reinforcing the common belief that web 2.0 has no technology foundation but rather a buzzword created by marketers.  The Differences between Web 1.0 and Web 2.0 Tim O’Reilly observed the differences between web 1.0 and web 2.0 from a consumer perspective in his original essay: Web 1.0   Web 2.0 DoubleClick --> Google AdSense Ofoto --> Flickr Akamai --> BitTorrent mp3.com --> Napster Britannica Online --> Wikipedia personal websites --> blogging evite --> upcoming.org and EVDB domain name speculation --> search engine optimization page views --> cost per click screen scraping --> web services publishing --> participation content management systems --> wikis directories (taxonomy) --> tagging ("folksonomy") stickiness --> syndicationFrom Consumer Web 1.0 to Consumer Web 2.0    From an enterprise perspective, web 2.0 introduces a very different set of changes:  Web 1.0   Web 2.0 Browser --> Application Client Container HTML --> Declarative application markup HTTP(pull, unreliable) --> Push, pub/sub, reliable Application Server --> Mashup Server Appilcation Integration --> Enterprise Mashup/SOA Press release --> Corporate blogs Packaged software --> On demand/Saas Close source --> Open source Top down (dictatorship) --> Bottom up (democracy) Superbowl Ad/TV --> Google AdFrom Enterprise Web 1.0 to Enterprise Web 2.0 The Two Pillars: Consumer Web 2.0 and Enterprise Web 2.0 Web 2.0 has two pillars: consumer web 2.0 and enterprise web 2.0. These two do overlap, in particular, in the area of social computing. Consumer web 2.0 and enterprise web 2.0 have different characteristics, as shown below: Consumer Web 1.0   Enterprise Web 2.0 Architecture of Participation Architecture of Partition Social networking On Demand computing/SaaS Harness collective intelligence Enterprise social computing HTML Mashup Enterprise mashup Rich User Experience Rich User Experience The Web As Platform The Web As PlatformKey Characteristics of Consumer Web 2.0 and Enterprise Web 2.0 The technology paradigm shifts with web 2.0 brings tremendous, tangible and measurable ROI to corporate IT. Further, the new possibilities enabled by web 2.0 such as social computing are bringing corporate IT to new horizons.
