Web 2.0 refers to the second generation of web development and web design sometimes viewed as a new version of the internet.  It has helped to create many things like blogs, wikis, video sharing and social networking sites.  The term was brought up at the 2004  O’Reilly Web 2.0 conference.  Web 2.0 is the network as platform spanning all connected devices.  Web 2.0 websites allow users to do more than just retrieve information, also allows users to run software-applications entirely through a browser. The term suggests a new version of the Web, it does not refer to an update to anything technical, but rather a change in the way software developers  utilize the Web.   Web 2.0 is not very well defined. It’s more a term that describes the latest revolution of Internet interfaces, including design and user interaction.  A lot of content control is given to users in Web 2.0 applications, such as with YouTube, FaceBook and MySpace.  Design in Web 2.0 is cleaner and leaner, as a general rule, such as with most popular blogs.  The concept of “Web 2.0” began with a conference brainstorming session between O’Reilly and MediaLive International.  Dale Dougherty, web pioneer and O’Reilly VP, noted that far from having “crashed”, the web was more important than ever, with exciting new applications and sites popping up with surprising regularity.  It also bring openness of data and services, to contrast with closed data that still exist today.  One of the most highly touted features of the Web 2.0  is the rise of blogging.
