Week 5 - Wiki

So wiki is a site where you or anybody else can add or edit information on a topic of your interest, and you can set up your own new wiki. The examples of wiki out there are just overwhelming. They are really useful cuz they provide collective knowledge and experiences which people post on the wiki to share with others. However the down side is that the information might not be well grounded as it is added by any individuals. So a good wiki site has to be one that is under some professional control.
