Great Uses for Social Bookmarking

I like to read David Warlick's 2Cents Worth blog and the comments that people make on it. In one of his posts I found a comment about presentations and also a comment with a link to using social bookmarking. Specifically, the comment referred to using del.icio.us and linked to another blog about uses for del.icio.us in the classroom. There are lots of good suggestions here and I think it's worth your time to read it. I'm going to post a link to it on the calcurriculum wiki as well.
