From footnote 19 of Crispin v. Christian Audigier, Inc. United States District Court, C.D. California. May 26, 2010, 717 F.Supp.2d 965:
It is unfortunate that the parties were unable to provide more authoritative evidence. One court recently noted the danger of relying on Wikipedia:
“Wikipedia.com [is] a website that allows virtually anyone to upload an article into what is essentially a free, online encyclopedia. A review of the Wikipedia website reveals a pervasive and, for our purposes, disturbing series of disclaimers, among them, that: (i) any given Wikipedia article ‘may be, at any given moment, in a bad state: for example it could be in the middle of a large edit or it could have been recently vandalized;’ (ii) Wikipedia articles are ‘also subject to remarkable oversights and omissions;’ (iii) ‘Wikipedia articles (or series of related articles) are liable to be incomplete in ways that would be less usual in a more tightly controlled reference work;’ (iv) ‘[a]nother problem with a lot of content on Wikipedia is that many contributors do not cite their sources, something that makes it hard for the reader to judge the credibility of what is written;’ and (v) ‘many articles commence their lives as partisan drafts' and may be ‘caught up in a heavily unbalanced viewpoint.’ ” Campbell ex rel. Campbell v. Secretary of Health and Human Services, 69 Fed.Cl. 775, 781 (2006).
See also Badasa v. Mukasey, 540 F.3d 909, 910 (8th Cir.2008) (noting that Wikipedia is not a sufficiently reliable source on which to rest judicial findings for the reasons stated in Campbell); Kole v. Astrue, No. CV 08–0411–LMB, 2010 WL 1338092, *7 n. 3 (D.Idaho Mar. 31, 2010) (“At this point, it must be noted that, in support of his brief, Respondent cites to Wikipedia. While it may support his contention of what the mathematical symbols of ‘<’ and ‘>’ refer to, Respondent is admonished from using Wikipedia as an authority in this District again. Wikipedia is not a reliable source at this level of discourse. As an attorney representing the United States, Mr. Rodriguez should know that citations to such unreliable sources only serve to undermine his reliability as counsel”); R. Jason Richards, Courting Wikipedia, 44 TRIAL 62, 62 (2008) (“Since when did a Web site that any Internet surfer can edit become an authoritative source by which law students could write passing papers, experts could provide credible testimony, lawyers could craft legal arguments, and judges could issue precedents?”); James Glerick, Wikipedians Leave Cyberspace, Meet in Egypt, Wall St. J., Aug. 8, 2008, at W1 (“Anyone can edit [a Wikipedia] article, anonymously, hit and run. From the very beginning that has been Wikipedia's greatest strength and its greatest weakness”). Judge McDermott accepted the information, however, and the parties do not dispute it now. The court will therefore consider the evidence presented to Judge McDermott as that is the content of the record on appeal.
