Hate site no longer top Google search result for "MLK"For the longest time — even through last year's Martin Luther King Jr. Day — a Google search for the term "MLK" produced as a top result MartinLutherKing.org, a site run by a white-supremacist organization called Stormfront. No longer. But why did the hate site ever appear as a top result in the first place?

Blame lazy librarians. Google's PageRank algorithm determines a website's relevancy to a keyword by crawling the Internet to find out how many times that particular site is linked to on other sites and how often that keyword is used to describe the link. Most of the pages that used to link to MartinLutherKing.org were written by librarians, hoping to package good source lists for researching students.
