These words are being used more and more. Of course, it was just a matter of time before the popularity and creativity of “Web 2.0” as a buzzword was reused, extended, and blatantly copied for other innovations in the technology space.

Like Web 2.0, the definition for Enterprise 2.0 can be debated, and will become debated more as it picks up speed and popularity. In my mind, Enterprise 2.0 refers to the unique Web 2.0 solutions and services that are especially relevant, sometimes “uniquely relevant”, to the enterprise.

Many times, this would include collaboration and social networking capabilities within an intranet. Blogs, wikis, and content tagging are a few of the Web 2.0 categories that come to mind, and all of this gets combined with the unique presence needs of Enterprise 2.0 environments where instant communication and collaboration within the organization is built into each feature.

Along with the push from Oracle’s User Interaction category of products within Fusion Middleware, I would also keep my eye on Google’s Open Source Google Wave technology, which has a very Web 2.0 interface with the ability to be extended into enterprise use.
