I am sure we all know someone who likes to prove a point by posting up a Wiki link, then sitting back all smug and conceited like they have proved you wrong about something, because it says so on Wiki, so it must be true. Or is it?
Don't they realise that anyone can add anything they want to that site? That anyone can then come along and edit it? And at the end of the day it is just the opinions of who ever edits. People don't even check the sources of the information, and if they do they don't find the source of that source. Any good researcher must research the source of the source until they get to the bottom of where some information or misinformation has come from. Otherwise you are just passing on someone else's opinion.
Wikipedia can be a useful tool and starting point for any kind of research, but it is not the end point, or the proof. Wikipedia is used as a source of proof by the intellectually challenged.
My point is, don't believe everything you read on Wiki, just as much as you shouldn't believe everything you read in the papers or see on the TV.
There are people out there who want to keep you in the dark, I am not one of them.
