Microsoft just launched Page Hunt, a game that presents web pages to players and asks that they guess key words to hunt them down. In the past, RWW has covered a number of search relevancy projects that incorporate human computational power including Semanti. But few projects have been presented to volunteers in such a fun and easy way. Sponsor Once a game begins, players are presented with a web page and receive points to guess keywords for the pages in the top 5 results.
