O’Reilly has a document on “What is Web 2.0?“. For class on Tuesday, please read the article as it really encapsulates the movement in web application design/architecture.
The important topics discussed are:
- Web as a Platform
- Harnessing Collective Intelligence
- Data is the Next Intel Inside
- End of the Software Release Cycle
- Lightweight Programming Models
- Software Above the Level of a Single Device
- Rich User Experiences
Of particular note is the comparison between a Web 1.0/Web 2.0 comparisons:
