An impressive amount of information on Wikipedia is just outright wrong, misleading, clearly biased, or astroturfed. At the rate in which I encounter inaccurate data on Wikipedia that I can identify, it makes me suspicious of nearly everything on the site. It's an interesting experiment to allow the masses to create and edit their own facts and it can provide a broad (albeit often inaccurate) overview of some topics, but it's hardly a substitution for a legitimate source let alone encyclopedia.
Nonetheless, I know plenty of people who take it as legitimate and cite it as if it's an authority.
