Social Bookmarking

Social Bookmarking

The proliferation of Web 2.0 tools has inspired the development of a number of applications designed to enhance collaborative work. Notable among these are social bookmarking systems. From a social network platform, they serve as an organizational tool to collect and organize a variety of web resources (hyperlinks, documents, podcasts, video files, graphics, etc.).² Social bookmarking has advantages over the traditional schemes, principally because it relies on a web-based system of classification known as folksonomy. Tags are collaboratively created and managed to annotate and categorize web content.

Social bookmarking sites first appeared about 10 years ago, but did not gain wide popularity until the launch of Del.icio.us in 2003. Among the many sites available today, Delicious and Diigo are the two most commonly used .ineducation

• One key difference between Delicious and Diigo is annotation. The latter allows users to highlight any part of a web page and attach sticky notes to specific highlights or to a whole page. These annotations can be kept private, shared with a Diigo group, or forwarded as a special link to other individuals or groups for collaborative purposes. Table 1 compares the main features of Diigo, Delicious, and traditional browsers.³
