The cited Wikipedia Bibliography for "Web 2.0" provides a solid definition of the Web 2.0. It described as the version of the internet we use today. Which mean you can actively interact with websites instead of just reading them. It's often called the "participative social web" because it lets you create your own content and share it or connect with others on platforms like Facebook, YouTube, and Wikipedia. This evolution turned the web from a one-way information source into a collaborative space.

The text says the user interface is what you view and interact with. My question is what do we call the part of the system that the user doesn't see? For example, the algorithm that decides what order posts appear in user's feed is a huge part of user experience. But it's not part of the UI. Is there a specific name for that "behind-the-scenes" part?

This chapter looks at the numbers we use for counting and measuring. It introduces the definition of "imaginary numbers" and "complex number" which were invented to solve problems that were previously impossible. The chapter shows how all different types of numbers work together and what properties they have.

This idea really resonates because it shows how technology designs force people to fit into boxes. For example, a freelance worker or gig worker using a professional networking site will be constantly prompted to list a single, current "Position" and "Company." This design assumes traditional full-time employment for every user, forcing them to choose one gig from their portfolio. And list themselves in a way that actually not accurately represent their flexible career.

The article provides a vivid description of how the click farm works and how it becomes a popularity machine. A full room of smartphones, and every phone switches IP address frequently. These phones are controlled by a central computer, and automatically like and follow to boost content. This article also shows an example of how such operations are deployed for political ends. And reflects on how quickly social metrics can shape people's perceptions of legitimacy.

This description raises a question for me about the ethics of "good faith". This chapter implicitly frames this as a bad activity. But what about researchers, archivists, or accessibility advocates whose goals are aligned with the public good, but who are forced to use these methods because the official API is too restrictive and expensive? And sometimes it may simply doesn't provide the data they need or just lack of enough functionality?

I do not fully agree with this idea. While living harmoniously with others and honoring communal relationships is important, this argument is too asserted. This is because it lacks a system for evaluating other people. If you only care about making good relationships without considering their actions, you will compromise too much and enter an unequal relationship. This ethnic framework somehow neglecting human's subjectivity.

In the early Han dynasty, Emperor Gaozu employed the ideas of Taoism, which is also known as "Rule by doing nothing." He recovered the economy after the war by implementing minimal management. This is a very good example of an ethical framework also serving as a strategy for governing.
