Can Wikipedia be trusted?

I think that Wikipedia can be trusted as a starting point for information. To gain basic understanding of a subject, Wikipedia could be very useful. Wikipedia should not be used as a main source of information because anyone could edit the information. This information is checked but not often enough to make Wikipedia a reliable source for research. I believe that it should remain exactly the way it is but users should be wary of how much they rely on the information they find there. If Wikipedia ever registered who gives the information, they would have to pay people to publish this information. This would mean that Wikipedia would no longer be "the free encyclopedia". When more reliable research is needed, users should look to another site.
