Coined by Dale Dougherty and Tim O'Reilly two years ago. The term took hold in 2005. Rather than defining it, they gave this example, "DoubleClick was Web 1.0; Google AdSense is Web 2.0. Ofoto is Web 1.0; Flickr is Web 2.0."

Web 2.0 Principles:
- The value of the software is proportional to the scale and dynamism of the data it helps to manage.
- Teverage customer-self service and algorithmic data management to reach out to the entire web, to the edges and not just the center, to the long tail and not just the head.
- The service automatically gets better the more people use it.
- Adoption is driven by "viral marketing". The greatest internet success stories don't advertise their products.
- Network effects from user contributions are the key to market dominance in the Web 2.0 era.
- Support lightweight programming models that allow for loosely coupled systems.
- Think syndication, not coordination.
- Design for "hackability" and remixability.
- Services, not packaged software, with cost-effective scalability
- Control over unique, hard-to-recreate data sources that get richer as more people use them
- Trusting users as co-developers
- Harnessing collective intelligence
- Leveraging the long tail through customer self-service
- Software above the level of a single device
- Lightweight user interfaces, development models, AND business models
