Now I’ve been speaking at (mostly Java) conferences for a while (six years now), I get asked to present at a lot of conferences. Obviously all these conferences are mostly interested in my terribly educational talks, but it’s also because I’m a technical woman and there aren’t very many technical women speaking at conferences.
In my experience, conferences want to do the right thing - they want a diverse line up of speakers, they want to attract diverse attendees. Often this is not as easy as it may seem, and frequently conferences are Twitter-shamed for not having enough women speakers. When it gets to this point (and often before), conferences frequently ask me for advice on speakers they could invite, and how to attract more women.
