With the launch of Askville, Amazon's joins the growing list of websites where users can ask fellow surfers answer to their question. Other similar services include Microsoft Live QnA, and Yahoo Answers.
So, what’s the difference? Askville researchers earn a virtual currency called Quest Coins, which can be redeemed at a forthcoming Amazon site called Questville. Points are awarded for questions and the quality of answers, but are deducted for answers rated inadequate by others users.
However, Quest Coins have already attracted criticism. An Askville Blog posting noted: "Some users have expressed concern about users asking numerous questions just to earn Quest Coins.
"If you read our FAQ, you will discover that the best way to earn Quest Coins is to provide great answers. In the long run, your hard work will be handsomely rewarded."
