Oh, I couldn't agree more! I still feel that Meredith was, by far, the best moderator the show ever had. I'd choose Rosie O'Donnell as second but I don't think she'll even be a guest again, much less the moderator.
My memory of the Nicole Wallace year was that she was supposed to be there for the conservative point of view but they sat her next to Whoopi who seemed to really like her. It was like she and Whoopi became buds.
