I can't provide specifics for the above claim, but SEOmoz's Search Engine Ranking Factor's survey found Recency (freshness) of Page Creation the 2nd most important factor outside of keywords. http://www.seomoz.org/article/search-ranking-factors#ranking-factors http://www.seomoz.org/article/search-ranking-factors#ranking... Also...SEOmoz just published an interesting experiment exploring the role of freshness.
