Although the coverage of the 2004 Indian Ocean earthquake has generally brought a lot of favorable publicity for Wikipedia, an incident last week illustrated instead its potential for spreading misinformation and highlighted the need to cite sources when writing articles.
The furor began with a story in the 31 December 2004 issue of the Washington Post. In that day's issue, reporter Jose Antonio Vargas wrote a piece entitled "Seeking the Hand Of God in the Waters". Near its conclusion, the article contained the following statement: "Following the devastation in Lisbon in 1755, priests roamed the streets, hanging those they believed had incurred God's wrath."
Vargas' article was part of the media coverage following the 2004 Indian Ocean earthquake, and drawing analogies to a very similar event that hit Lisbon in 1755 fit in quite naturally. It apparently struck a chord, and this particular statement was picked up and repeated in some form by many different sources in the following days.
