Wikipedia and the Age of Information Overload

My son recently had to do some research on the original Buddah, Siddhartha Gautama.  He spent quite a lot of time searching all over the internet because his class was specifically warned by the teacher about the hazards of using information from Wikipedia.   The crazy thing was that the Wikipedia page about Buddah was seemingly so much more robust than other references to Gautama.   Was that because it was full of misinformation?  Actually, it had many references embedded within it and was a good starting point for my son's project.  If anything it was too complete and after looking at it with him for a short while, my head began to hurt from the sheer volume of information contained within it.

I understand that Wikis can be updated by just about anyone which makes the information suspect.  No longer is there tight control over information (either the quantity or the quality) but does that mean that the information lacks integrity?  In the case of Buddah, much of the same information on Wikipedia was found in other articles.  By not using Wikipedia, my son had to do a lot of digging.  Did he learn anything from the experience?  Only (according to him) that his teacher is purposely trying to make their lives more difficult by disallowing Wikipedic information.  Maybe students' time would be better spent on teaching them how to evaluate prospective internet resources instead of simply disallowing the use of Wikipedia.  Who knows, it may be the most valid and correct of all the information out there.  But alas, since he was unable to use Wikipedia he spent time searching everywhere else and ended up using a different resource.  But whose to say that one is correct either.

I found this video of two late elementary/middle school age students discussing similar issues regarding the use of Wikipedia with their teacher and thought it was interesting. 

Ok, so I was going to have you watch a video, but I can't get it to work right.  So after two hours of screwing around with this crap here is what I look like:
