Some of you may have noticed that I am incapable of looking at a list of books and wondering what percentage of those books were written by women (evidence here and here) so when Nay asked me to help her crunch the data on a project she was doing for ladybusiness about the gender breakdown of speculative fiction reviews on book blogs, my answer was "Where do I sign up?" I futzed with Excel and made her some charts, and the post with her results went up yesterday. It's some pretty fascinating (and sometimes discouraging) stuff. The upshot is that, while the overall percentages don't look too bad (about 40% of the authors reviewed were by women), there seem to be stark differences between the reviewing habits of women and of men.
