CONCLUSIONS

• Wikipedia is Community

• Wikipedia is most useful as a quick and simple way to find basic reference information. It will never be a source of primary literature.

• Wikipedia is, by and large, accurate most of the time. However, until some formal validation process is introduced, the information can not be considered 100% reliable.
