Le Web 2.0

The web 2.0 is a word created in 2004 by Dale Dougherty of the O'Reilly Media corporation and popularized in 2005 by Tim O'Reilly. In an article entitled What is web 2.0 ?, the author redefines the Internet not only as a simple media but as a medium of collective intelligence. A true revolution seating the user in the heart of the Internet and marking for some the return to the fundamentals, for others a vast swindle.

For users, it means more participative tools than can be acquired. For developers, it means formats, standards, technologies eanbling to link systems. In a marketing vision, it covers the notion of services in wich users create contents as well as the economic pattern where free is the rule.

2. Abolished borders

The web 2.0 abolishes borders: sites and services are no longer isolated islets of information. They communicate and enable multiple re-combinations:
  • between applications (inter-operability, applications combinations...): calendars, maps...
  • between medium (computers, telephony, audio reader, video, Internet), with the advent of teh web as main channel.

3.Improvement of interfaces

Interfaces become more ergonomicthanks to the simplification of actions: fewer clicks ("slide/put down"), more comfort (automatic recording of modifications).

4. The webisation of desktop applications

Traditional apps leave local desktops to join webtops. Expl: "Office live" from Microsoft

5. An unstable sector

Sites and services refering to web 2.0 do not stop increasing. Services are free or accessible at very low cost. The great majority of corporations proposing 2.0 services have less than 24 months...
