Cool new group blog: the Geek Feminism Blog, featuring Liz H, Sumana H, and a bunch of other interesting writers. (I wasn't previously aware of most of them, but I like what they're writing.)
Their About page says, among other things:
The Geek Feminism blog exists to support, encourage, and discuss issues facing women in geek communities, including [...] science and technology, gaming, SF fandom, and more.
The entry that appears to've gotten the most attention so far is "Where are all the men bloggers?", a send-up of Where are the women bloggers? posts. The in-character comments on the "men bloggers" post are particularly entertaining, at least up until people who didn't realize it was a joke started posting comments.
See also the followup post for further discussion and explanation.
