No doubt, Wikipedia's anyone-can-be-an-expert nature means that it, too, can get things wrong. The site also gets its share of pranksters. Recent entries have noted that a popular computer game was written by Mr. T, of television's "The A-Team" (not), and that one of the prime suspects in the assassination of John F. Kennedy was John Seigenthaler, Sr., the founding editorial director of USA Today (beyond not). The key to using Wikipedia, say its supporters, is understanding Wikipedia: It's a jumping-off point for research, a place where users get background on a topic, and links to authoritative sources. It is not, on its own, a definitive source. Even Wikipedia's founder, Jimmy "Jimbo" Wales, has advised college students not to use the site for serious research. In comments made to BusinessWeek in September, patent commissioner John Doll said that Wikipedia had been used for background only, and not as a basis for accepting or rejecting applications.
美國專利商標局規定Wiki只能背景參考，不能作為專利核駁的依據。Wiki創始者Jimmy "Jimbo" Wales也如此建議使用者。
