Title: Wikipedia: My Free Treasure Trove of Knowledge and Learning Companion  
Introduction  
In the internet age, there are countless ways to acquire knowledge, but Wikipedia remains my most trusted free encyclopedia. Whether I need to quickly verify a concept or dive deep into a subject, Wikipedia always provides a wealth of information. Today, I’d like to share what I’ve learned from Wikipedia and how it has transformed my approach to learning.  
 1. Breadth of Knowledge: From History to Technology, It Covers Everything
Wikipedia encompasses almost every topic you can imagine. For example:  
- History: I once used Wikipedia to explore the detailed history of the "Silk Road," including its trade routes, key cities, and its impact on cultural exchange between East and West.  
- Science: When learning about "CRISPR gene editing," Wikipedia not only explained its principles but also listed key scientists and ethical debates.  
- Trivia: Did you know? Bananas are technically berries, while strawberries are not! Fun facts like these make my everyday conversations more interesting.  
Wikipedia is like a massive library—no matter what I want to learn, it offers a reliable starting point.  
2. Multilingual and Global Perspectives
Wikipedia is available in over 300 languages, allowing me to understand topics from different cultural viewpoints. For instance:  
- Different Narratives of the Same Event: Entries about "World War II" in Chinese, English, and Japanese may emphasize different aspects, teaching me to view history more holistically.  
- Language Learning: I often read scientific articles on the English Wikipedia, which helps me gain knowledge while improving my English reading skills.  
3. Real-Time Updates: Keeping Up with the World  
Wikipedia’s editors are incredibly efficient—major news often appears as entries within hours. For example:  
- When ChatGPT first gained popularity, Wikipedia quickly provided detailed explanations, including its technical background, applications, and controversies.  
- During the COVID-19 pandemic in 2020, Wikipedia’s entries were updated daily with the latest data and research developments.  
This made me realize that Wikipedia isn’t just a static repository of knowledge but a dynamic information hub.  
4. Cultivating Critical Thinking  
Although Wikipedia is incredibly useful, it has also taught me how to assess the reliability of information:  
- Checking References: I’ve developed the habit of reviewing cited sources at the bottom of articles to ensure credibility.  
- Comparing Multiple Versions: For controversial topics (e.g., climate change, political events), I compare entries in different languages to see how various perspectives are presented.  
Wikipedia doesn’t tell me "what’s right"—it teaches me **how to find answers on my own.  
5. Wikipedia’s Limitations  
Of course, Wikipedia isn’t perfect:  
- Not Suitable as a Sole Academic Source: Professors usually require citations from original papers or books, not Wikipedia, for research papers.  
- Incomplete Coverage of Niche Topics: Some highly specialized or obscure subjects (e.g., "an obscure 18th-century painter") may only have brief summaries.  
Still, it remains an excellent **starting point for learning.  
Conclusion: How Wikipedia Changed Me  
Wikipedia has shown me that knowledge isn’t confined but is collaboratively built by countless volunteers worldwide. It’s not just my "go-to reference tool" but also a key that sparks curiosity. Every time I stumble upon an unfamiliar entry (like "quantum tunneling" or "Maya civilization"), it opens the door to a new learning journey.

Introduction to the blog

This blog is a digital forum where students from Collective Intelligence in Practice: Understanding Wikipedia at the Hanyang University in Korea (2025) will discuss their weekly readings and activities. Each week you are expected to post a blog post on our blog and make a comment on another student's post. You can do so on one of the following three topics: a) You can blog about the readings for the next week. As you are expected to do the assigned readings FOR the lectures they are assigned to, you are expected to post your blog and comments BEFORE that lecture. An ideal commentary should be about half a page in length (~200 words), divided into three clearly labeled sections in which you: 1) summarize in your own words of materials you read; 2) mention any new, interesting, or unusual items learned; 3) identify at least one question, concern, or discussion angle that is either problematic in some respect or could have been elaborated more. This question is likely to be incor...

Week 1. My Recent Wikipedia Edits - Jeong seolah (정설아)

I made several edits to the Wikipedia page for 'Daegu'.  Daegu, located in the southeastern part of South Korea, is the third-largest urban area in the country, following Seoul and Busan. With a population exceeding 2.3 million, it is the fourth-largest metropolitan city in South Korea and the second-largest in the Yeongnam region after Busan. Often referred to together with the surrounding North Gyeongsang Province as Daegu-Gyeongbuk, this region is home to over 5 million residents. Known for its rich history and vibrant economy, Daegu stands as a key player in South Korea's cultural and industrial landscape. Below is a summary of the changes I contributed. 1) Summarize and link Sights Section:  - Improved clarity by changing “mountains keep many traditional temples” to “the mountains keep many traditional temples.” Mosque Controversy Section:  - Simplified a sentence by removing “and of the authorities.” Festivals Section:  - Made phrasing smoother by changing “tho...

Week4 - Review about the readings for the next week. - Jo HyeonSeong (조현성)

 1. Summarize in my own words of materials. The book is primarily about the openness of Wikipedia. Openness means that anyone can participate in the creation and editing of articles without any qualifications. Openness can be a double-edged sword. While it means that you can edit without having expert knowledge of a topic, it also means that you can participate even if you have expert knowledge. For experts, articles written by non-experts can come across as inaccurate knowledge, which can anger experts. This anger can also be a catalyst for Wikipedia to continue to improve. However, articles edited only by non-experts can cause misunderstandings and convey incorrect information, so openness can be considered a double-edged sword. In fact, it sometimes causes some conflict, such as Wales' negative stance. Openness also means freedom from copyright, which means anyone can take it and use it anywhere. That is why the knowledge of non-experts can have greater impact. That is why appro...
