How many times have you listened to an instructor diatrabe on the evils of Wikipedia? And how many times have you used Wikipedia as a quick start to a research project or to look up some oddball fact? Really, Wikipedia is here and we all use it. Sure, there are factual errors, but on average it's pretty good. (And there are factual errors in peer reviewed studies and documents also.) A few mistakes are not a valid reason to throw the whole thing out. What they are a valid reason for is teaching our students how best to use Wikipedia. And that's not a lot different from teaching our students how to use any encyclopedia. It's not peer-reviewed and it's not a primary source. You go there to get a good overview and to look at the citations.
