You know, Little Brother was the only one of those that even came close to being what I'd consider a Hugo award nominee based on the kind of challenging, exploring and fairly unique stuff that used to get nominated. What in the world happened?
edit: And I'm not really trying to be provocative

I like the authors that are nominated. I've read good things by all of them and I've heard 3 of them are extremely nice folks and haven't heard anything bad about the ones I don't know about. I guess I've just noticed a difference all of a sudden.
