I've always found the discussion of male/female writing styles interesting, because I like to watch it in myself and my partners. I find that, when I write, I tend to focus very heavily on actions and concrete thoughts; I set the stage like one might the script for a movie. I describe what's seen, what thoughts are passing through their head, and the key elements for a scene. If a scent is important, it's added. If it doesn't play into the mood, the setting, I'm trying to evoke, it doesn't get mentioned. Similarly, I prefer to try to get emotions across through words and actions, and not by using the words. It's hard to explain, but it feels... hamfisted, to, for example, say "Jane, smiling, happily said, 'I'm so happy!'" That may be a bit of an extreme example; what I'm referring to is far more subtle. But I'd prefer to have something more along the line of "Jane smiled. 'I'm so happy!'" Same words, very different... connotation, even though I only changed a tiny bit around.
Female writers, I find, tend to go into more subtle descriptions. They might describe how she was feeling, how it affected her, leaving the smiling to be assumed. I think that may be the difference; I assume emotions that come tied to actions, women assume actions tied to emotions. [/stream-of-consciousness-rambling]
