RSS feeds are new to me. I've often noticed the icons, and even clicked on it once or twice without knowing what I was doing. I can certainly see the advantages of having all my regular updates in one spot. My igoogle page already provides some of these features (and the Google Reader can be added to that page - how nice!) so the idea is not entirely new. I like that I can get updates all at once, especially those pages I would like to visit but don't always have time to do so. This is incredibly helpful for those of us in the information profession who need to stay current on as much as possible, but also have numerous time-consuming responsibilities in addition to educating ourselves.
In addition to all of our class blogs that I am following, my feed includes both fun and informative subscriptions. CNN.com, Comedy Central's Joke of the day, Readers Club Latest (book reviews), Simply Recipes, and Unshelved (librarian comics & jokes - suggested by the 2.0 tutorial). Since I also use Google for e-mail, I can share my subscriptions and view those of my friends through gmail. I'm sure I will get new ideas for my own RSS from this kind of sharing.
