A couple of points. AP may have "moved on" from Brokeback Mountain but recently she revisited it and wrote the libretto for the opera that will debut in Spain in 2013, something I'm looking forward to very much.
In her audio interview with the BBC (I've been trying to find the link to it without luck) AP said how disappointed she was with The Shipping News...with the movie and also with the book, even though it won the pullet surprise. She was influenced by public feedback on her work to add a happy ending which she did grudgingly and she added "if you can define happiness as an absence of pain." A very complex and inscrutable person! With my training and degree in journalism, I respect her need to tell stories about rural life as it is and was. There's a need for entertainment, but there's also a need for what she gives us, like it or not.
