TIME Person of the Year 2004: 10 Things We Learned About Blogs:
"Most Bloggers Are Women
Men may have taken the lead in the early (read: geeky) days of blogging, but that's not the case now. According to a survey of more than 4 million blogs by Perseus Development, 56% were created by women.

We knew it all along, didn't we, Ladies?
