Other than that, I don't know, she's just too big a personality to sort of disappear and let the kids be the stars. The others (even Simon) aren't really "star" personalities who seem to need to be in the spotlight a lot.
The only think that would be good is if she really does challenge Simon in any intellignt way or oppose him and make sense (unlike Paula).
Good points. I'm sure she's going to make more sense than Paula though, that won't be hard!
Wasn't Ellen a pretty big Kris fan too? She seemed pretty thrilled when he went on her show. Not to say that she wasn't a big Adam fan, because she was, but I think maybe she wouldn't necessarily only say the things that are "approved" by TPTB.
SleepinIn, did you watch Glee? I'm going to watch it now. Too bad my DVR was working weird and didn't record the first three or four minutes...
