So, do we live in a celebrity-obsessed culture or are celebrities obsessed with journalism?  Next Thursday, Nightline will air a report from none other than Ben Affleck. The actor apparently approached the program with the idea of doing the report as a way to raise awareness about the violence, starvation, and disease that is so prevalent in the region.  Affleck joins a long list of celebrities that have tried their hand at journalism, including U2 frontman Bono, who edited an issue of Vanity Fair last year and Sean Penn, who wrote a series of articles about Iraq for the San Francisco Chronicle.
