“The site has created what it calls “The Movie Genome” – a database of movies tagged by a team of humans aided by a computer algorithm, with attributes spanning fifty categories. The database is reminiscent of Pandora’s Music Genome Project (which is also sorted by human professionals), though it is significantly smaller at this point. Users can either search for movies based on a manual search, browse through movies by their attributes, or can generate recommendations after completing a brief test that determines their movie personality. After finding a movie or show they’re interested in, users can buy or rent them (or in some cases, watch them free) through a number of linked services, including Hulu, Amazon, and Netflix.”
You can join the beta over at their site… click the picture if you’re interested.
