What is Web 2.0?
Web 2.0 is a term that distinguishes the post-dotcom bubble era of the World Wide Web from its earlier form. It emphasizes social networking, user-generated content, and cloud computing. The term, inspired by software naming conventions, gained popularity after a series of Web conferences organized by Tim O'Reilly in 2004, but its popularity declined in the 2010s as its features became common.
Web 2.0 is characterized by technologies, platforms, and services that enable individuals to engage in many-to-many communication. Everyone in the network can simultaneously produce, distribute, and consume content. Social media's power comes from the connections between its users, allowing them to coordinate activities at unprecedented scales and speeds.

How is Web 2.0 different from the earlier version of the web?
Web 2.0 marks a shift from the earlier, "read-only" Web 1.0 to a more interactive and user-driven experience. It is characterized by features like social networking, user-generated content, and cloud computing.
Unlike Web 1.0, where content was primarily created and controlled by website owners, Web 2.0 emphasizes participation and collaboration. Social networking sites, such as Facebook and Myspace, became popular, allowing users to connect, share content, and create online communities. The rise of user-generated content, seen in amateur reviews on sites like Amazon, also exemplifies this shift.

How do users interact with Web 2.0 sites differently than with older websites?
Web 2.0 sites emphasize user-generated content, social networking, and cloud computing, distinguishing them from their predecessors. Users of Web 2.0 can engage in communication from one-to-one, one-to-many, and many-to-many configurations.
Web 2.0 enables every network participant to simultaneously create, distribute, and consume content. The connections among users and the ability to coordinate activities at unprecedented scales and speeds also characterize it. The rise of the "produser," who both uses and creates online content, exemplifies the shift from audiences to participants, fostering increased user autonomy, participation, and diversity.

What new features or technologies made Web 2.0 possible?
Web 2.0's emergence involved technologies that enabled user-generated content, social networking, and cloud computing.
Key advancements included:
* AJAX (Asynchronous JavaScript + XML) This programming model allowed web pages to update dynamically without full reloads, creating more interactive user experiences.
* JavaScript Enabled developers to add dynamic elements to the client side of applications, improving speed and user experience.
* HTML5 An updated version of the programming language used to create Web pages, improving the functionality of browsers.These technologies, combined with the rise of social media platforms, shifted the Internet toward user-focused, decentralized, and collaborative environments.

How has Web 2.0 changed the way people communicate and share information online?
Web 2.0 marked a shift in how people communicate and share information online by emphasizing social networking, user-generated content, and cloud computing. It enabled individuals to engage in communication from one-to-one, one-to-many, and many-to-many formats.
The rise of social media platforms like Facebook, Twitter, and YouTube exemplifies this shift, allowing users to be simultaneous producers, distributors, and consumers of content. This has led to increased user autonomy, participation, and diversity in online content creation and sharing.

Web 2.0, term devised to differentiate the post-dotcom bubble World Wide Web with its emphasis on social networking, content generated by users, and cloud computing from that which came before. The 2.0 appellation is used in analogy with common computer software naming conventions to indicate a new, improved version. The term had its origin in the name given to a series of Web conferences, first organized by publisher Tim O’Reilly in 2004. The term’s popularity waned in the 2010s as the features of Web 2.0 became ubiquitous and lost their novelty.
At the first conference in 2004, the term was defined by “the web as platform.” This, however, was augmented the following year with a still more nebulous expression incorporating the idea of democracy and user-driven content, especially as mediated by the Internet. In particular, many of the most vocal advocates of the Web 2.0 concept had an almost messianic view of harnessing social networking for business goals.
One of the most influential concepts of democratization was due to Chris Anderson, editor in chief of Wired. In “The Long Tail,” an article from the October 2004 Wired, Anderson expounded on the new economics of marketing to the periphery rather than to the median. In the past, viable business models required marketing to the largest possible demographic. For example, when there were few television networks, none could afford to run programs that appealed to a limited audience, which led to the characteristic phenomena of programming aimed at the lowest common denominator. With the proliferation of satellite and cable networks, however, mass marketing began to splinter into highly refined submarkets that cater better to individual tastes.

Similarly, where traditional brick-and-mortar bookstores could afford to stock and display only a limited range of titles, Internet bookstores such as Amazon discovered that total sales of niche titles actually exceed those of mass-market best sellers. The vast quantity of niche books makes up for the greater sales of a few popular titles—makes up, that is, in the new digital environment of e-commerce, where counter space is no longer limited.
Amazon.com was also a leader in adopting user-created content. One of the appeals to shopping at Amazon’s site was the inclusion of amateur book reviews, with users being able to leave personal perspectives and interact with other reviewers. An even more successful business example of user-created content came from electronic games. Many companies found that, by including simple programming tools with their games, ordinary gamers could create modifications, or mods, and new scenarios that generate as much or more interest as the original game and thereby extend its lifetime sales. This strategy proved especially effective in conjunction with Web sites that host players’ games and forums for exchanging ideas and files.
An exact definition of Web 2.0 proved rather elusive, in part because the concept encompassed different goals and expectations for the future of the Internet and of electronic publishing in general. A leading critic of the Web 2.0 concept was Web inventor Tim Berners-Lee, who pointed out that
Web 1.0 was all about connecting people. It was an interactive space, and I think Web 2.0 is of course a piece of jargon, nobody even knows what it means. If Web 2.0 for you is blogs and wikis, then that is people to people. But that was what the Web was supposed to be all along.
That is, social networking had always been central to the Web, for, according to Berners-Lee,
The trusted destination for professionals, college students, and lifelong learners.

Web 2.0…means using the standards which have been produced by all these people working on Web 1.0. So Web 2.0…means moving some of the thinking client side so making it more immediate, but the idea of the Web as interaction between people is really what the Web is. That was what it was designed to be as a collaborative space where people can interact.
In contrast, Berners-Lee advocated the development of the Semantic Web, which some visionaries call part of Web 3.0.
