Filmaster (now in public beta mode and available under filmaster.com) is a new social network for movie fans, with personalized content and recomendations. And all that free as in beer and as in speech. Filmaster allows you to run your own film blog in a great domain like you.filmaster.com, rate movies and talk about movies with people whose opinions you care about. Personalized recommendations are a bonus.
Filmaster is being developed as an open source project (using django framework) and everyone is welcome to participate!
