Although the term suggests a new version of the World Wide Web, it does not refer to an update to any technical specifications, but rather to changes in the ways software developers and end-users utilize the Web.  Web 2.0 websites allow users to do more than just retrieve information.  They give the user the ability to interact with the site choosing what they want to see and how they want it presented. 

The term "Web 2.0" describes the new trend in web design created to enhance your online experience.  Web 2.0 is constantly evolving and includes communications, secure information sharing, collaboration and functionality of the web. Web 2.0 developments have led to the evolution of web culture communities and hosted services, such as social-networking sites (MySpace and Facebook), video sharing sites (YouTube), wikis (Twitter) and blogs (Blogspotter).
