This would be great but for a librarian who doesn't have much time to read and is too frugle to purchase books I'm not sure. I did like looking at the reviews about the books I entered. I couldn't figure out how to add the LibraryThing link.
Digg - I am not sure how to digest so much information. I still prefer to find information at a major news source and then decide if I want to go deeper. I decided not to register. I am feeling overwhelmed with all of this informtion.
