Is that what this is about?

You're a woman and you regularly write about your life and about issues of inequality. I don't think much more can be asked of you. I don't think the answer is to come up with some sort of composite portrait of the average woman and her interests and then go and find someone to write diaries matching those interests. Or is it?

"Women's topics" is whatever it is that women discuss (yes, it sounds like circular reasoning but it is not). Therefore the way to get more women's topics on the site is for the existing women on the site to lead more discussions in it. And a diary is just that, an excuse for group discussion.

You said elsewhere it's not as simple as just writing more, but there is no other way.
