From the BOOKFORUM interview with Gore Vidal:
BF: You write in Point to Point Navigation that you were once a "famous novelist," by which you don't mean you've stopped writing novels. You say, "To speak today of a famous novelist is like speaking of a famous cabinetmaker or speedboat designer."
GV: Yes. There's no such thing as a famous novelist.
BF: But what about a writer like Salman Rushdie?
GV: He's moderately well known, but he's not read by a large public. He's very good, but "famous" has nothing to do with being good or bad.
BF: A few critics have declared the American novel dead.
GV: I don't think the novel is dead. I think the readers are dead. The novel doesn't interest anybody, and that's largely because there are no famous novelists. Fame means that you are touching everybody or potentially touching everybody with what you've done—that they like to think about it and talk about it and exchange views on it.
