I may as well weigh in, since everybody else in the world has.
I’m not a hater; in my teens, I watched Late Night with Conan O’Brien and enjoyed it. But if I’m watching anything at 11:00, it’s The Daily Show.
Late night talk shows seem kind of like some television relic to me. I know they still draw ratings, but we’re about thirty years beyond late night talk shows pushing any kind of envelope (The Daily Show is a different animal, because it’s political). There isn’t much that’s fresh about the format, so I hardly feel we needed a third pillar.
