The term web 2.0 became popular in 2004. This term refers to the second generation of the World Wide Web, characterized by user-generated content, social media platforms, and interactive web applications.

The popularity of web 2.0 grew as more people began actively participating in online communities and sharing information on platforms like blogs, social networking sites, and video-sharing websites.

A trackback is a type of backlink that allows one website to notify another website when it has linked to it. It is a way for websites to communicate and reference each other's content. When a trackback is received, the linked website can display a notification or a link back to the referring website. This helps to create connections and promote collaboration between different websites in the online community.

The term "Wisdom of the crowds" refers to the idea that the collective knowledge and opinions of a large group of people are often more accurate and reliable than the expertise of a single individual. This concept applies to web 2.0 because it emphasizes the importance of user-generated content, collaboration, and collective intelligence. In web 2.0 platforms, such as social media, online forums, and review websites, the contributions and feedback from a diverse group of users can provide valuable insights and information that surpass the expertise of a single expert.

A tag refers to a keyword that users attach to content. This allows for easy categorization and organization of content, making it easier to search for and find related information.

The correct answer is that a blog is usually centered around one person, while a wiki is many to many. This means that a blog is typically written and maintained by a single individual, who shares their thoughts, opinions, and experiences. On the other hand, a wiki is a collaborative platform where multiple users can contribute, edit, and modify the content. It allows for a collective knowledge-building process, where multiple perspectives and inputs are welcomed.
