I think replacing Paula Abdul with Ellen DeGeneres on American Idol is pure crazy talk.
I personally like shows where the judges actually have some knowledge/experience about the topic they are judging. Perhaps I don't know about Ellen's successful singing career? Her successful record label? Maybe she's lived in Detroit or Nashville? Or, maybe, sometime in her past, she has listened to the radio, and that is all it takes to be a judge on American Idol.
I hope next year they replace Simon with Steve Carell.
