Thing 17

I have thought a long time about the whole wiki...thing. Wiki spaces, wikipedia, etc. On the one hand when it comes to information in this, the information age, most often it would stand to reason that more is better. More people contributing means more information. Then it occurred to me that information is only as good as the integrity of the people posting it. I could add to a wiki space on brain surgery but the information would be far less than reliable. If a wiki were limited to only those you knew had knowledge on a certain topic, then it would be fine. To me that would be more like just collaboration on a topic or web site. True wikis that can be edited by virtually anyone are only as reliable as the people posting the information. I may be a bit skeptical, but in this time of people hacking into computers and creating viruses, worms, and Trojans, what is to keep them from sabotaging a wiki site?
