We’re told that Facebook will be launching its joint project with Comcast’s Ziddio, Facebook Diaries, at about 9 p.m. tonight. The eight-episode weekly series spotlights topics like heartbreak, road trip, and wild nights, with pilot episode “Who Am I” already queued up at http://www.facebook.com/diaries.

Facebook has been playing around with the project for a while now since announcing it in February, even shooting some of its own video, but the series will be completely user-contributed clips, with editing and motion graphics by producer R.J. Cutler of Actual Reality Pictures.

Randi Zuckerberg, a two-time NewTeeVee Pier Screenings runner-up (and sister of Facebook CEO Mark Zuckerberg), is one of leaders on project.
