[/INDENT]But as you've explained, Teresa, this caricature is far from accurate (so I won't quote Bones on the subject ).
Not accurate at all. In my day at least (she says, shaking a gnarled finger), most of them had spouses and families and good jobs in IT — unless they were associated in some way with publishing — but instead of spending hours watching sports and pursuing a variety of hobbies, all of their interests and almost all of their socializing brought them into contact with people who shared their passion for books, movies, television, gaming, science, and history.
Of course Ian is far more familiar with what goes on in the SF community these days than I am. Because, actually, I don't have a life anymore.
But back to the subject: I think almost any editor, agent, writer, or professional reviewer in the SFF field would give very similar definitions for hard and soft science fiction. And the same would be true for the people who go to the conventions and subscribe to the magazines.
And you know, while there are certain problems with labeling books and sticking them into neat little niches, it sure is convenient when discussing them if everyone speaks the same language.
Look at all the different definitions that people are coming up with in this thread. The discussion is interesting, but how could you hope to communicate with someone who has wildly different definitions that you do if you were asking them for recommendations?
