Wikis can be very useful in education today. I have used Googledocs many times in my undergrad studies and it made it so much easier when communicating to a group of people for an assignment. Rather than the traditional email where some emails could go overlooked or read out of order or even being worked on at the same time, a wiki allows students to edit the exact same paper for other students to see. This allows a group paper to be done for everyone to see it quick and not after one of the group members formats it and sends it to everyone else. Wikipedia is said to be the largest wiki and it is a good and bad wiki. It is good because there is a lot of information on almost any subject you can possibly think of. It is bad because it is unregulated and anyone can access the information and change it. This includes people who know nothing about a certain subject but still post information about it.
