This is one of the reasons that at PES Network we aim to have a peer review article (not editable by community) for each of the major wiki articles.

Wikipedia != Authoritative?
Posted by CmdrTaco on Sunday September 05, @08:02AM from the well-duh-people dept. Frozen North writes "Recently, this article in the Syracuse Post-Standard caused a stir by dismissing Wikipedia as an authoritative source, and even suggesting that it was a little deceptive by looking too much like a "real" encyclopedia. Techdirt suggested an experiment: insert bogus information into Wikipedia, and see how long it takes for the mistake to be removed. Well, I did that experiment, and the results weren't good: five errors inserted over five days, all of which lasted until I removed them myself at the end of the experiment."
