Monday Technology Tip- Wikipedia
This will be a very short tip, but hopefully that will make the point clearer. Wikipedia is not a reliable source of information. Ironically even doctoral candidates do not understand this.
While the information is often correct, it should not be treated as authoritative. Anyone can edit articles and clearly not everyone knows what they are talking about. It is definitely useful for supplemental information and to point you in the right direction, but always use an authoritative source to back up your work. What I do like it for is background information for something that is new. It can be a great source of information for many things that you want to add to your collective knowledge but realize its limitations.
