I have played around in the past with RSS feeds and do think that they are a useful tool for the classroom as well as for general knowledge. In today's society, information overload occurs easily, and RSS feeds are one way to limit where you get your information from. I did not make my URL known publicly, however for this particular class I did find it useful to add my classmate's blogs to my RSS feed in order to view and comment on new posts more efficiently. In a library setting, you can subscribe to the RSS feeds of other librarian's blogs as well as newsfeeds in order to stay current with offerings and help locate subject specific information that patrons may want. I found it quite easy to import my google reader subscriptions into my blogger account so that everything is in one place and easy to find.
