Interesting story here in Wired about how Overstock.com used Mahout to build and deploy a recommendation engine to replace RichRelevance, thereby saving $2 million in annual fees.
Overstock joins an elite list of companies who are monetizing Mahout. including Adobe, Amazon, AOL, Buzzlogic, Foursquare, Twitter and Yahoo.
