This could have passed unnoticed. In a post about Dell an the fact their online shop was more 2.0 than their ideagora Ideastorm, Tim O’Reilly made his definition of web 2.0 seriously evolve from the original one.
For your information, here his the “original” defintion as it can be found on wikipedia today.
Web 2.0 is the business revolution in the computer industry caused by the move to the Internet as platform, and an attempt to understand the rules for success on that new platform.
A visionnary definition that was victim of the too many interpretations it allowed and gave rise to techno-centric trends. If the web’s flexibility made it possible to get out of that, adapting the definition to the enterprise’s world, aka enterprise 2.0, which was something like “using blog and wikis within the enterprise” did more harm than good to the E2.0 concept, even if Andrew McAfee refind the termis of its definition from the use of web 2.0 tools within the enterprise to the use of emergent social tools within the enterprise and with clients and partners as I noticed in Montreal in may.
In brief, O’Reilly introduced a major evolution of its vision. Even if I often find discussions about definitions more funny than useful, what this one implies deserves that we have a closer look at it.
