Having completed his role as producer of Metallica’s Death Magnetic, music svengali Rick Rubin is reportedly on the verge of joining the board of social networking/music blogging site MOG. The music site has already accrued two million users since its July 2006 launch, and the addition of Rubin in whatever capacity Rubin will serve would only assist in giving MOG some cred amongst music lovers. MOG has already raised $6 million in funds, including contributions from Sony and Universal Music, and are planning on revamping their site to be both ad-supported and easier-to-use. Rubin is already employed by Columbia Records to find up-and-coming unsigned artists, but his job there doesn’t preclude him from joining an internet venture. Despite being a “music network,” MOG doesn’t actually play that much music (kind of like MTV), instead giving music fans a forum to discuss and read about their favorite artists, albums and songs.
