I don't consider wikipedia a reliable source, when it comes to certain subjects. Almost all articles can be edited by anyone.

Wikipedia (play /ˌwɪkɪˈpiːdi.ə/ or /ˌwɪkiˈpiːdi.ə/ WIK-i-PEE-dee-ə) is a free,[3] web-based, collaborative, multilingual encyclopedia project supported by the non-profit Wikimedia Foundation. Its 17 million articles (over 3.5 million in English) have been written collaboratively by volunteers around the world, and almost all of its articles can be edited by anyone with access to the site.[4] Wikipedia was launched in 2001 by Jimmy Wales and Larry Sanger[5] and has become the largest and most popular general reference work on the Internet,[2][6][7][8] ranking seventh among all websites on Alexa and having 365 million readers.[9][10]
