Site Operation
Yahoo! Answers allows any question that does not violate Yahoo! Answers community guidelines. To encourage good answers, helpful participants are occasionally featured on the Yahoo! Answers Blog. Though the service itself is free, the contents of the answers are owned by the respective users – while Yahoo! maintains a non-exclusive royalty-free worldwide right to publish the information. Chat is explicitly forbidden in the Community Guidelines, although categories like Politics and Religion & Spirituality are mostly opinion. Users may also choose to reveal their Yahoo! Messenger ID on their Answers profile page.
To open an account, a user needs a Yahoo! ID but can use any name as identification on Yahoo! Answers. A user can be represented by a picture from Yahoo! Avatars or an uploaded picture. When answering a question, a user can perform a Yahoo! or Wikipedia, or any source of information that the user wishes, as long as they mention their source.
Questions are initially open to answers for four days. However, the asker can choose to close the question after a minimum of one hour or extend it for a period of up to eight days. To ask a question, one has to have a Yahoo! account with a positive score balance of five points or more.
The points system is weighted to encourage users to answer questions and to limit spam questions. There are also levels (with point thresholds), which give more site access. Points and levels have no real world value, cannot be traded, and serve only to indicate how active a user has been on the site. A notable downside to the points/level system is that it encourages people to answer questions even when they do not have a suitable answer to give to gain points. Users also receive ten points for contributing the "Best Answer" which is selected by the question's asker or voted on by the community. Contributors often vote for their own answer regardless of its quality or appropriateness. At the same time, many questions are posed by the asker without any real desire to gain knowledge. In addition to points awarded for activity, Yahoo! Answers staff may also award extra points if they are impressed with a user's contributions. The Yahoo! Answers community manager has stated that "power users" who defend the company should be thanked and rewarded.

Famous quotes containing the words site and/or operation:
“That is a pathetic inquiry among travelers and geographers after the site of ancient Troy. It is not near where they think it is. When a thing is decayed and gone, how indistinct must be the place it occupied!”
—Henry David Thoreau (1817–1862)
“An absolute can only be given in an intuition, while all the rest has to do with analysis. We call intuition here the sympathy by which one is transported into the interior of an object in order to coincide with what there is unique and consequently inexpressible in it. Analysis, on the contrary, is the operation which reduces the object to elements already known.”
—Henri Bergson (1859–1941)
