Amazon just sent me a notice that they have a new site, named "Askville", where I can "ask a question, get real answers from real people" http://askville.amazon.com/askville/CIndex.do?id=5#answers . Hmmm. When I checked some of the answers and what was sourced for each answer, I will continue to go to my own favorite place where I can ask a question and get a real answer from a real person - the library.
