The newly launched Yahoo! Answers makes a retributive slap at the long-established Google Answers, while reinforcing Yahoo!'s commitment to community. Google Answers, one of Google's least-known services, offers professionaly researched solutions to all sort of queries, using a bidding system to determine how much the customer will pay the researcher. All queries and answers are archived in a directory for informative browsing. The service really should be better publicized, because it contains a treasure chest of knowledge. One of the coolest features of Google Answers is that anybody can chip in an answer, and the amateur answers sometimes give the professional answers a run for their money.
