Here is something you can do.
Contribute to this fabulous Kickstarter campaign:
Donate $5 or more to get some goodies and help this along if you're so inclined, and help Lightspeed publish an all-woman-authored special issue chock full of science fiction. Now that the campaign has reached $28k, funding will also go toward the release of an all-woman-authored issue of Nightmare Magazine, Lightspeed's horrible sister (and my favourite). One more major stretch goal remains: if they reach $35k before the campaign closes on February 16, they'll release an all-fantasy issue. I would love to see that.
Read more about it in this essay by Christine Yant, guest editor of the Lightspeed special issue. If you can't donate, you can always signal boost. Bless your little heart if you do.
ETA February 13, 2014: The reason why this Kickstarter is so important might not be evident to some of you. In the comments I've pointed to some of the more recent events that might have inspired this campaign, but the best place to go to learn more is the Women Destroy Science Fiction update list, which contains many amazing essays by women about their experience writing and reading science fiction. (You don't have to contribute to the campaign to read the updates.) Like horror, science fiction is considered by many to be a man's domain. The attitudes of many who create, publish, and consume these genres is often hostile to women.
If you ain't got time for that, please just take a look at Maya Kaathryn Bohnhoff's essay in which she discusses the reception of some of the fiction she published in Analog. Here's an especially salient bit if you don't want to click through:
ANALOG’s longtime editor, Stan Schmidt, has told me he’s lost subscriptions over my work. I knew this before I attended my first Worldcon in 1992 and was still gob-smacked when a couple of fellows cornered me at a party and explained, at length, why I had never written a word of real, hard science fiction in my life and, therefore, did not belong in the pages of ANALOG. This was after only half-a-dozen stories. I’m at two dozen and counting.I don't want to be in the business of accumulating proof that this Kickstarter is a wonderful reaction to a sad, longstanding problem, but I get it if you've never encountered this issue and you don't know how to research it, I do want to help. As I writer, I'm all too familiar with how just the act of writing alone is hard enough, without worrying about how your stuff will be received or if it will be perceived as less valid because you fall into a certain category of personhood. As a reader, I am very invested in reading genre fiction that expresses a diversity of opinions. I already know what I think, and we all know what sort of story a male-dominated industry thinks is good (hello, Hollywood filmmakers). I want to know what you think. Yes, you. If your stuff is being blocked for being "too different," that's a tragedy as far as I'm concerned. I'd like to see that changed.
