The clearest and most delightful use of social bookmarking that I've found is its ability for to help me keep track of the resources I find in the course of my surfing. It makes it so easy to store and organize data - just a click on the toolbar and a few typed words, and I never have to wonder where I saw that excellent article, or that great blog with all the amazing links.
Additionally, as with movie or book reviewers I've come to trust, there are other taggers who's taste in websites I appreciate, who's tags I check on to see if they've updated. I don't really check the most popular tags, though I've heard that some people do, I find it's more useful to me to follow people who are interested in the same things that I am.
I took a class in interactive narrative last semester, and we used social bookmarking in a cooperative project. It was an extremely creative use of the medium, and it was fun and inspiring. I'd definitely use it with a class. All the students started on the same website, and bookmarked an image. Then they had to surf, by direct linking, to another website and chose an image there to bookmark, and so on, until there were 30 bookmarks. Those 30 were given to a fellow student, and that student had to create a narrative, written or visual, from the bookmarked images. My images are under the tag 251 project, and my partner, Spencer Hargiss, created the most amazingly funny video from them. I will post it here, if I can get his permission.
My question would be, in what other ways could one use social bookmarking in lesson plans? I'm trying to think of ideas that are unexpected and playful, as well as taking advantage of the obvious peer to peer learning potential.
