I can't say I ever watched his show faithfully, but the times I caught it, he always impressed me with his very easy personality. He seemed to be totally at ease, and sounded like he was talking to his audience as individually as he talked to his guests. He seemed also to be a very likeable guy, very down to earh and very approachable, nowhere near as full of himself as some of these other talk show people can be.
My sympathies to his family, friends, and colleagues. He showed a level of class and professionalism not very common in the field these days. Let's all sit back and catch the pictures as they fly through the air... He will be missed.
