Wikipedia has a fairly strict policy requiring all articles to be written from a neutral point of view (NPOV). In fact, this is one of the five fundamental principles of their site:
Wikipedia is written from a neutral point of view.
We strive for articles that document and explain the major points of view in a balanced and impartial manner. We avoid advocacy and we characterize information and issues rather than debate them. In some areas there may be just one well-recognized point of view; in other areas we describe multiple points of view, presenting each accurately and in context, and not presenting any point of view as "the truth" or "the best view". All articles must strive for verifiable accuracy: unreferenced material may be removed, so please provide references. Editors' personal experiences, interpretations, or opinions do not belong here. That means citing verifiable, authoritative sources, especially on controversial topics and when the subject is a living person.
Does the same policy apply to Philosophy.SE? Are questions and answers required to be written from a strictly neutral point of view, or are we allowed to express our own opinions?
What is the policy here with regard to:
- The necessity to present all points of view or otherwise conform strictly to a neutral point of view?
- Citation requirements for answers?
- The acceptability of original research or one's own experiences?
- The general style and tone of posts?
