I love love love my feed reader. I use Google Reader, and have a widget that exports it to my iGoogle page (right next to my current BestWidgetEver, MyListy).
Primarily I use it for work-related stuff, though that includes the more librarian-y of my library friends blogs, and yes, my Sunday PostSecrets are there to make Mondays more bearable. But mostly it's a "current awareness" service for work-related things.
Yay Feed Readers! And now I'm off to add some of you to my reader!
