From a report at the first link below:
Shortly after the news broke that the conservative political radio talk show host was hospitalized, Wikipedia updated his page – and pronounced him dead.
If the report is correct, Wikipedia was prepared for the worst when it came to Rush Limbaugh. Maybe a little too well prepared.
Rush Hudson Limbaugh III (pronounced /ˈlɪmbɔː/;born January 12, 1951, died December 30, 2009) is an American radio host and conservative political commentator. He is the host of The Rush Limbaugh Show, the highest-rated talk-radio program in the United States. It airs throughout the U.S. on Premiere Radio Networks.
Rush, although in a Honolulu hospital, was very much alive. About 15 minutes later Wikipedia pronounced him alive, altering their bio by removing the information that he had died.
This illustrates what can happen when it doesn’t take much more than a computer, Internet service and a word processor to post nearly anything you want on Wikipedia - the most quoted yet least accurate site on the web.
Top illustrate just how bad Wikipedia is, founder Jimmy Wales has warned students not to refer to Wikipedia as it can seriously damage their grades (see third link below).
