In Web 2.0, users are not only information receivers but also information producers, which means that data flow is bidirectional.

The interaction required by Web 2.0:

1. Web 2.0 encourages users to create and share content, such as blogs, videos, photos, etc., which significantly improves user participation and interactivity.

2. Web 2.0 supports the development of social media and online communities where users can share information, exchange opinions, and interact. This model based on user-contributed content and social interaction greatly enhances the attractiveness and stickiness of the website.

3. Asynchronous JavaScript and XML is one of the core technologies in Web 2.0, which enables Web pages to update content without refreshing, thereby providing a smoother user experience.

4. Representational State Transfer provides a standardized way to access Web services and supports data interaction and sharing. This promotes data exchange and integration between different network applications.

Differences from today’s internet:


1. Dynamic vs. static: During the Web 2.0 era, websites enhanced their interactive capabilities, enabling users to share and interact with content. Today’s internet has further developed on this foundation, introducing more advanced technologies such as artificial intelligence and big data, making websites and services more intelligent and personalized.

2. User Engagement: Although Web 2.0 has significantly increased user engagement, today’s internet has further lowered the barriers to content creation through platforms like social media and short videos, enabling more users to participate in content creation and sharing.

3. Data Security and Privacy Protection: As users increasingly prioritize data security and privacy protection, today’s internet places greater emphasis on compliance and security in data processing and storage.

4. Personalization Settings: Users can customize the platform’s interface and features and push content according to their preferences and needs. For example, in some news and information apps, users can choose news channels they are interested in to receive information updates that better meet their needs.

5. VR and AR: These technologies, such as virtual meetings and augmented reality games, provide users with a completely new immersive experience.
