Web 2.0

Web 2.0
Web 2.0 is a version of the original World Wide Web introduced by Tim Berners-Lee. This implementation of the web was created in late 2004. While the web originally acted as a way for individuals to send files form one place to another, web 2.0 acts as the first implementation of the semantic web that focused on user-generated content. One of the driving points for this new type of web was that of social media. Websites such as Facebook, and Myspace created ways for users to represent themselves online and share files seamlessly with other web users. With this new user-centered focus on the Web comes the issues of user privacy and tracking of personal user information.

Characteristics of Web 2.0
Web 2.0 created ways for users to interact with the files they read. Instead of simply reading a document on a web page, Web 2.0 created using HTTP ways for users to comment on other peoples files, or create their own user account within a website. This type of web design allowed users to take control of the internet that they interact with daily. This implementation of the web also used HTML elements to style the layout of a web page. While this strive for a more involved internet system was necessary, it also brought with it a number of complications. While Web 2.0 allowed users to develop, share, and operate their own hypermedia content, their information was being gathered online through the use of web cookies and other information tracking elements. Another issue that arose with the arrival of Web 2.0 is that of harmful social behaviors.

While users were able to interact with one another anonymously or with someone else's identity, individuals were able to say and do whatever they want online with limited repercussions This has led to an increase in cyber crimes.
