The Wikipedia article Atomic Bombings of Hiroshima and Nagasaki includes 84 footnotes, a fairly good demonstration of how reliant Wikipedia is on external sources. It also includes 92 links to pages on other sites that the authors either used as references or felt offered further useful information on the topic.
Wikipedia, with its nofollow strategy, is telling Google that every one of those sites is equal in importance to a spam site. Is that a good thing? Is that even an appropriate thing, given how heavily Wikipedia used information from those sites in its article?
