our purposes, disturbing series of disclaimers...". Such disclaimers include the Wikipedia not being able to guarantee the validity of the information on its articles and having no formal peer review. Among other reasons for these statements about Wikipedia's reliability are the stability of the articles (which due to editing may cause new readers to find information that differs from the originally cited) and, according to Stephen Gillers, a professor at New York University Law School, "the most critical fact is public acceptance", therefore "a judge should not use Wikipedia when the public is not prepared to accept it as authority". Wikipedia has also become a key source for some current news events such as the 2007 Virginia Tech massacre, when The New York Times cites Wikimedia to report 750,000 page views of the article in the two days after the event: The Washington Post commented, in the context of 2008 presidential election candidate biographies, that despite occasional brief vandalism, "it's hard to find a more up-to-date, detailed, thorough article on Obama than Wikipedia's. As of Friday (14 September 2007), Obama's article—more than 22 pages long, with 15 sections covering his personal and professional life—had a reference list of 167 sources." Broad opinions Several commentators have drawn a middle ground, asserting that the project contains much valuable knowledge and has some reliability, even if the degree is not yet assessed with certainty. Others taking this view include danah boyd, [sic] who in 2005 discussed Wikipedia as an academic source, concluding that "[i]t will never be an encyclopedia, but it will contain extensive knowledge that is quite valuable for different purposes", and Bill Thompson who stated "I use the Wikipedia a lot. It is a good starting point for serious research, but I would never accept something that I read there without checking." Information Today'''s March 2006 article concludes on a similar theme: Dan Gillmor, a Silicon Valley commentator and author commented in October 2004 that, "I don't think anyone is saying Wikipedia is an absolute replacement for a traditional encyclopedia. But in the topics I know something about, I've found Wikipedia to be as accurate as any other source I've found." Larry Sanger stated on Kuro5hin in 2001 that "Given enough eyeballs, all errors are shallow", which is a paraphrase of Linus' Law of open-source development. Likewise, technology figure Joi Ito wrote on Wikipedia's authority, "[a]lthough it depends a bit on
