Thing #4 RSS Feeds

I've never tried RSS feeds before, mostly because I didn't understand their intended purpose. Now after registering for google reader I can see how it would be a great time saver if there's certain sites you like to keep up with daily. It's very easy to set up and the search tool in google reader is a great way to add subscriptions.
I can see how this could be useful in the library world, in keeping up with library news, authors, new releases, etc. all in one place.
