In the classroom, RSS is valuable to a teacher who needs to manage time while searching internet sites.  RSS gives the teacher the capability of looking at several titles, and then choose what they wish to view.  It allows them to put specific topics into files for further use.  It allows a teacher to follow specific blogs by simply subscribing to their news feeds.  Another use for RSS is to follow their students blogs.  This would be a great way to track a journal from each student. 

The Reader that I am using Google Reader.  I have actually subscribed to all of the people in the class.
