Can people trust Wikipedia

I tell students that it is a good place to start but you better find a back-up source

A:

Although WikiAnswers is fortunate enough to have professionals that may supervise or simply contribute to the site along with individuals that may have acquired specific knowledge that enables them to accurately answer questions asked, it is open to anyone that wishes to participate. Therefor a wide array of people use and contribute to the site which allows for some mischief to exist such as changing the Wording of answers of even making them misleading. Not too much is set in stone as the absolute final answer, thus making it the falable and jewel of a site that it is.
