W3. Why do you think people use Wikipedia? Why do others write for it?

I think the reason why people use Wikipedia is related to how Wiki works. All men have a desire to know deeper knowledge. On Wikipedia, people can develop their knowledge by editing articles or by discussing with others. As we know, Wikipedia is operated by many people's collaboration. we can improve our knowledge and also provide more information on wiki for free. And also This process of exchanging opinions is regarded as contributions of human being's knowledge and making better world. These aspects of Wikipedia become more attractive the more we use it. And compared to other websites' searching, the information on Wikipedia is easier to find sources and references, so it can be trustworthy. These are the reasons why people use Wikipedia and write for it, I think.
