Abstract The web is rapidly becoming both more open and more social through the provision of technologies that make it easier for end users to access resources and join in social networks. Social networks have pioneered online communities, allowing users to contribute to collective knowledge by tagging online resources. Tagging behavior increased dramatically between 2005 and 2007. This article reports on an investigation of social tagging using data gathered from Delicious, Flickr and YouTube for the years 2005, 2006 and 2007. Preliminary findings indicate both that it is possible to profile a social network through the analysis of tagging data and that Delicious is a more representative venue for analyzing the social tagging behavior of users than either Flickr or YouTube.

Forum improvements; a continuation of our collaborative effort with the Moodle User Association that started for Moodle 3.7. We are now introducing a range of new features that make Moodle Forums substantially more powerful. Teachers are now able to grade their students’ forum contributions with the introduction of the forum grader functionality. Student activity can be reviewed with the new forum summary report and forum content can be exported for further analysis. We have also introduced a new user preference where you can select to use a new design for the nested discussion view. Try it out and let us know what you think!
