A quote on the mainstream

From Dave Langford's inestimable fanzine Ansible:

"I think I know what people mean when they say they don't write sf. They mean they don't write sci-fi--i.e. Star Wars, Star Trek and so on. I believe there's been a bit of a shift in the use of the terms, these days. My guess is that most of the people who say they don't write sf wouldn't think Phil Dick wrote sf either. Of course, that could just be me being kind. Given that social fiction is now essentially a minority taste and that sf and fantasy are the dominant forms of fiction, should we be worrying about these distinctions? Mainstream means marginal, doesn't it? It's not we who are still in the ghetto." -- Michael Moorcock
