I love the idea of the RSS being the new paperboy. It is so true. To be able to have all the blogs I subscribe to available in one spot is so convienent. I personally have been using Google reader for about 6 months and I am still learning new things that it can do. The share feature and also the email feature are great. I subscribe to the Mental Floss blog and I am constantly sharing posts with my husband via email.
The blogs that I subscribe are so varied, so it is nice to have them in one place. I could probably set up a RSS feed for just school stuff.
I think Google Reader would also be a good RSS to use at school. It is easy to use and has very helpful tutorials for all levels of users.
