I have been lax in my duties as a fangirl and have not yet linked to
Girl-Wonder.org. It will come as no surprise to anyone, I'm sure, that there is sexism in comics. g-w.org is dedicated to changing that, and unlike many movements of this sort they're motivated by love for the medium. They're just starting up with a letter-writing campaign, but they're also hosting a collection of really interesting blogs and academic articles. I have a lot of respect for the women & men who are running this project; go and check them out!
Because capes aren't just for boys.
