A few days ago I started a thread here on physicsforums about a new article on climate change. Yesterday I was using google to find out more about some related research. To my surprise the thread I started was on top when searching using some but rather generic keywords. If you google using the search string "deadly blow", the thread I started is at nr. 3, even though the thread title was changed within hours by the moderator. How is this possible for such a generic search string as "deadly blow"?
