This is the policy on it.wikiquote; many Wikiquotes do not have a real
NPOV policy, but a simple import from Wikipedia. We found this policy
very useful to decide on difficult articles and train newbies, in some
months of application. In fact, that is the result of several years of
experience on Wikiquote. I think that it will be useful for you, too.
