Findory was a news and blog aggregation website that utilized collaborative filtering to provide users with personalized newsfeeds and news e-mails. Findory collected a history of which articles a user clicked, a form of passive filtering, to recommend articles preferred by similar users. Along with news and blogs, Findory provided personalized podcasts and video, personalized web search, and a variety of access methods, including a REST API, e-mail subscription, and mobile phone access.
Findory was founded in 2004 by Amazon.com alumnus Greg Linden. In January 2007, Linden announced that he would be abandoning new work on Findory, and that he planned to shut it down. Although the announced November 1, 2007 termination date was briefly postponed, the service ultimately ceased on December 18, 2007.
