Web 2.0 is the network as platform, spanning all connected devices; Web 2.0 applications are those that make the most of the intrinsic advantages of that platform: delivering software as a continually-updated service that gets better the more people use it, consuming and remixing data from multiple sources, including individual users, while providing their own data and services in a form that allows remixing by others, creating network effects through an “architecture of participation,” and going beyond the page metaphor of Web 1.0 to deliver rich user experiences.

In general, the World Wide Web has a high potential as a platform for distributed groupware systems. Authors create and change documents locally and upload them to a Web server, where they can be accessed by their collaborators. However, Web browsers and servers which implement the protocol HTTP are mostly limited to provide reading access to Web documents. For this reason, existing Web-based groupware systems (e.g. the BSCW system) are implemented using client/server side scripting. These scripts are used to implement the basic operations needed for this kind of applications.

The Web is constantly evolving and changing. In the beginning the Web was a click, wait, replace model. A user would type a Web address, and a page was loaded. To interact or get more details about the current topic the user would provide information via a form, click submit and wait for a new page to be downloaded. The foundation of the Web was to be able to share information. Until competent search engines were developed, the user would click on provided links to traverse the myriad of data. The Web opened up a vast world of knowledge to people. Except it was, and still is, very visually oriented and relies on the mouse interface to navigate.

Web search services are among the most heavily used applications on the World Wide Web. Perhaps because search is used in such a huge variety of tasks and contexts, the user interface must strike a careful balance to meet all user needs. We describe a study that used eye tracking methodologies to explore the effects of changes in the presentation of search results. We found that adding information to the contextual snippet significantly improved performance for informational tasks but degraded performance for navigational tasks. We discuss possible reasons for this difference and the design implications for the better presentation of search results.
