A key theme of the JISC Transforming Curriculum Delivery through Technology programme is the use of digital technology to transform the ways in which knowledge is represented and shared. Web 2.0 technologies allow communities of like-minded people to build and share their own resources, and there is no doubt that social networks and file sharing sites extend enormously the opportunities for informal learning. At the same time, there is evidence that only a small minority of users are engaged in productive activities such as contributing to wikis, building shared bookmarks and references, tagging and reviewing, participating in virtual worlds with an educational focus, and research-based online collaborations. In fact, most learners are still introduced to such activities through the formal curriculum.

The JISC LLiDA report on Digital Literacies , 'Thriving in the 21st Century' (2009) recommends that learners should have opportunities to encounter and communicate academic ideas in a range of different media, and to work on knowledge-based tasks with a range of others, again using different media to support collaboration.
