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.

In internet era, users think in terms of services not packaged software, and they expect these services to be just and to improve over time. Software has become a service – a service that is always on, always improving. Success now relies on adoption of the perpetual beta development model in which software is continuously refined and improved, users become co-developers and operations become a core competency. It is Web Development 2.0.

The complex and evolving technology infrastructure of Web 2.0 includes server-software, content-syndication, messaging-protocols, standards-based browsers with plugins and extensions, and various client-applications. These differing but complementary approaches provide Web 2.0 with information-storage, creation, and dissemination capabilities that go beyond what the public formerly expected of web-sites.
