Tracey and I are attending a Texas Blackboard User Group Preconference (T-BUG) called Frontier of Emerging Technology: How to incorporate social software in your courses. The presenter is Chris Bigenhoc.
Chris has given us some interesting information on tools. We have looked at many of them before, including blogger (what this blog is posted on!)
One to see is CiteULike, which is a place for "CiteULike is a free service to help you to store, organise and share the scholarly papers you are reading." Sort of a social peer review site for academic information.
