My experience is that tech conferences are mostly comprised of socially competent people. In a group of 20 people, for example, I might find that one person in a group is truly inept. So, to do the arithmetic for everyone, that's 5%. Unfortunately, that's often about the same percentage as the number of women present. :/
I won't lay out all of the problems with identification, getting the "socially inept" into one room and educating them, making sure that whoever is teaching this (as yet undefined) social skills curriculum is a good teacher, making sure the education sticks, etc... Instead, I'm just going to share that I don't think education of socially incompetent people will significantly improve my conference experience.
Things that help include:
* An assumption on the part of conference staff, speakers and attendees that women are there to participate, not just observe or tag along
* Swift, friendly, supportive responses from staff if verbal or physical harassment is reported - often made possible by staff who are aware of an anti-harassment policy, and are trained in what to do (LCA did a great job of this in 2012)
* Allies who help stop hostile, harassing and inappropriate comments if they occur
And there's other stuff that helps too. There's some good stuff in the "what can allies do" section of the Geek Feminism wiki.
Anyway, I appreciate your willingness to converse about this issue and hope I've shed some light on why people might be down-voting your comment.
