Answer Boards and Social Searching
I have once browsed Yahoo Answers hoping to find the answer for unlocking region code from my Hitachi DVD player, and found the answer for the particular brand and model. Thanks for the information, I successfully got my DVD player unlocked! On the other hand, it is true that a lot of answers provided are vague and based on personal opinion. So it would be fantastic that information professionals like librarians provide answers based on authoritative resources. But hang on, librarians are very busy people and full of questions at hands. So why they bother to go out to find more questions??
