Public Beta opens up for Windows Live QnA
Windows Live team has opened up Windows Live QnA for public beta.
Windows Live QnA blog has more details on it. Anybody having Windows Live ID can ask questions on it. One has the ability to ask questions and tag the questions as well. One can ask questions and the question will be open for 4 days by when others are expected to respond to those questions. Then people can vote for the best answer. There is a point system in place where answerer would get points to answer the questions. There are points, levels and reputation.
People are expected to live by a code of conduct while on the site. The more people follow these sites the more fun it can be, otherwise subject specialised forums is a good idea in my mind.
