This is a new service from the huge web services company Yahoo!. It allows you to easily post questions and get answers from other users. In that way it is pretty much like a forum apart from it is specifically geared towards questions and answers. So you can only post one answer to each question, the questioner can put the answers to a vote etc. A points system underlies the whole website to encourage people to use the system. As you move up the points ladder you can posts more questions and answers and get special gifts from the Yahoo team. It is called Yahoo! Answers and I think that it is fairly brilliant.
