RSS feeds Google reader

I'm now deep into RSS feeds, for better or worse.  I like the idea of having an automatic update of "stuff" I'm interested in.  However, it can add a lot of other unnecessary information and ads I don't want.  I can really see a use for this as part of the library webpage.  The catch is of course to make it so fascinating (or unpredictable maybe?) that the target audience (teachers? students?) will want to tune in.  Last year I used Bloglines so I tried Google Reader this year.  There are a LOT of feeds available now, one for everything you could think of.  I'm beginning to look for author/reading feeds.
