Social Bookmarking
This is a useful tool in the classroom. I run a computer lab, and we often have trouble personalizing the experience for each student. The idea of having a place where they can save useful links for future use is valuable. Students can also collaborate. So if there is a team all working on a similar topic then they can share what they have found and don't have to worry about losing the information if they switch computers or some one else deletes there files. I'm actively looking at adding this type of solution to some of the research projects that I have.

My one concern, though, is that schools will not approve of students participating in social networking sites.
