Like on Wikipedia, WikiAnswers.com users can harness the power of the wiki-model to improve content. Unlike Wikipedia, WikiAnswers.com is not an encyclopedia, it’s a question-and-answer system. Contributors are encouraged to add to and improve each other’s answers instead of asking and answering the same questions over and over again.
Contributors are encouraged to keep an eye out for vandals and spammers. There is also a team of over 500 volunteer Supervisors who are contributors especially dedicated to helping WikiAnswers.com Q&A grow in a collective and productive way.
