W5. Can we trust Wikipedia?

When I edit Wikipedia, I always put the reference on it as soon as possible. I think that putting a reference is giving the trust to Wikipedia's users. When they check the reliable reference, they might think 'this article is quite reliable!'. But we shouldn't exclude the case that someone could make a mistake paraphrasing. And someone add his/her subjective thinking unconsciously. And they might be add plausible gossip calculatedly. So we always need to talk and think about our collective knowledge. Wikipedia has a good system about that. So I Think the knowledge in the Wikipedia quite reliable.
