Stand-up comic Jena Friedman is joining the writing staff of Late Show with David Letterman this week. This is exciting for two reasons. One, Friedman is a hilarious and smart up-and-coming comic. Two, her addition to the writing staff marks the first time in Late Show history that more than one woman has been on the staff. A lot has been written in the last year about the dearth of women on major late night show writing staffs, and one can only see the hiring of Friedman as another step in the right direction.
