Well, not really. But he thinks Americana would have been, had he tried to sell it today. He speaks with the WSJ about Point Omega:
It’s tougher to be a young writer today than when I was a young writer. I don’t think my first novel would have been published today as I submitted it. I don’t think an editor would have read 50 pages of it. It was very overdone and shaggy, but two young editors saw something that seemed worth pursuing and eventually we all did some work on the book and it was published. I don’t think publishers have that kind of tolerance these days, and I guess possibly as a result, more writers go to writing class now than then. I think first, fiction, and second, novels, are much more refined in terms of language, but they may tend to be too well behaved, almost in response to the narrower market.
