A little while back, I was asked on twitter: if tech conferences are, for women, an experience that's dangerous at worst and uncomfortable at best, how do we go about fixing it?

This is rather a big question—basically akin to "how do we eliminate sexism in society?" Conferences are a microcosm of the larger world; they transmit most of its problems and amplify some to boot. That being said, I'm certainly happy to outline what I think some reasonable starting points for allies might be.
