Abstract :
Wikipedia, today the seventh most popular site on the Web, is the go-to source for untold millions of users around the world. Yet, despite widely publicized worries that the selfedited and self-policed encyclopedia might subvert authority, the opposite concern has also emerged. Does Wikipedia, in other words, provide a viewpoint that\´s overly mainstream, giving short shrift to controversial, minority, or heretical ideas? "All great truths," George Bernard Shaw famously wrote, "begin as blasphemies."
