To answer this question, you need to understand the key characteristics of Web 2.0. Let's go through each option to understand why it is correct or incorrect:

To answer this question, we need to understand the concept of "Wisdom of the crowds" and its application to Web 2.0.

Option A) Collective knowledge from many is of greater value than that of a single expert - This option is correct. The "Wisdom of the crowds" refers to the idea that the collective intelligence and opinions of a large group of individuals can be more accurate and valuable than the knowledge of a single expert. This concept suggests that when a diverse group of people independently share their opinions or make predictions, the average of their responses tends to be more accurate and reliable than an individual's opinion.

Option B) An expert opinion always outweighs that from a group - This option is incorrect. The "Wisdom of the crowds" concept implies that the collective knowledge and opinions of a group can be more valuable than that of a single expert, contradicting this option.

Option C) Experts can seek opinions from others to increase their wisdom - This option is partially correct. While it is true that experts can seek opinions from others to gain additional insights and perspectives, the core idea of the "Wisdom of the crowds" is that the collective knowledge and opinions of many people are inherently valuable, regardless of whether experts seek them or not.

Option D) Diverse collections of independently-deciding individuals require an expert to resolve conflicts - This option is incorrect. The "Wisdom of the crowds" does not necessarily require an expert to resolve conflicts. Instead, it suggests that the collective intelligence of a diverse group can often lead to accurate results without the need for an expert's intervention.

Therefore, the correct answer is A) Collective knowledge from many is of greater value than that of a single expert. This option aligns with the concept of the "Wisdom of the crowds" and its application to Web 2.0.

To answer this question, we need to understand the characteristics and differences between blogs and wikis.

Option A) Blogs have comments while Wikis do not - This option is incorrect. Both blogs and wikis can have comments. Comments allow readers to provide feedback or engage in discussions about the content of the blog post or wiki page.

Option B) Blog is an advanced form of a wiki - This option is incorrect. Blogs and wikis serve different purposes and have different structures. A blog is typically a platform for an individual or a small group to publish and share their ideas, opinions, or experiences. It is usually presented in a chronological format, with the most recent posts appearing at the top. On the other hand, a wiki is a collaborative platform that allows multiple users to create, edit, and organize content. It is not an advanced form of a blog but rather a different type of platform.

Option C) Blog is usually centered around one person, while wiki is many-to-many - This option is correct. Blogs are typically centered around one person or a small group of authors who share their individual perspectives or experiences. The content on a blog is usually presented in a personal or subjective manner. In contrast, wikis are designed for collaboration and knowledge sharing among multiple users. They allow many-to-many interactions, where users can create, edit, and contribute to the content collectively.

Option D) Wiki is usually centered around one person, while Blog is many-to-many - This option is incorrect. The statement is the opposite of the correct answer. As mentioned earlier, blogs are usually centered around one person or a small group, while wikis are designed for many-to-many interactions.

Therefore, the correct answer is option C) Blog is usually centered around one person, while wiki is many to many. This option accurately represents the typical characteristics and purposes of blogs and wikis.
