What is Web 2.0? A widely accepted explanation is that: Web 2.0 refers to a new trend of social web services that rely on communities to define and uncover the web. Personally, I disagree with this statement. I prefer to call this type of network Web 1.5, which is a critical step toward the Semantic Web. And it is the Semantic Web that I consider as the true Web 2.0.
**The core idea of Web 2.0:**
The essence of Web 2.0 lies in its focus on user-generated content, usability, and interoperability facilitated by technologies like AJAX, RSS, and APIs. It emphasizes the transformation of the web from a platform for merely consuming information to one where users actively participate, collaborate, and share. Web 2.0 fosters community-driven interactions, leveraging collective intelligence through social networks, tagging systems, and crowd-sourced platforms. Furthermore, it sets the stage for the Semantic Web by enhancing data structure and meaning, enabling machines to better interpret and utilize information. This progression ultimately aims to create a more intelligent, interconnected, and personalized online experience.
