Well, I use Wikipedia for research. But, I use it “in some limited situations . . . for getting a sense of a term’s common usage." Fire Insurance Exchange v. Oltman & Blackner, Case No. 201004262-CA, 2012 UT App 230 (Utah App. 2012)(discussing the uses and reliability of Wikipedia as a source of information).
See e.g., United States v. Jones, ARMY 20090401 (A. Ct. Crim. App. December 14, 2011), Appellant was accused of effectively “Equating MOS trainees to permanent party – grandmothers to toads” The court cites to Wikipedia for the proposition that the expression “WIKIPEDIA, http://en.wikipedia.org/wiki/Apples_and_oranges (a Serbian expression akin to the familiar "apples to oranges" idiom in English) (last visited Dec. 1, 2011); in United States v. Magalhaes, NMCCA 200602480 (N-M Ct. Crim. App. February 21, 2008), the court cites to Wikipedia for the definition of the Pythagorean Theorem; in United States v. Ober, ACCA again resorts to Wikipedia for discussion of Kazza one of the early “programs” used to exchange many things over the internet, but for our purposes CP (which was also done in State v. Ballard, 2012-NMCA-043, ¶ 19 n.1, 276 P.3d 976 (N.M. Ct. App. 2012)(citing Wikipedia to define "peer-to-peer file sharing").).
But the Fire Insurance Exchange court cites to these several cases and there is an interesting discussion of Wikipedia.
