My wife does talk about being a woman in tech, but not in conferences. And in general she says, "Whatever, use the term 'guys' if you want. It doesn't matter." She's more worried about people treating her differently (changing their speech patterns when she's around!) than anything else, I think.
The idea that women should work remotely so they can cry if they get upset is... Horrifying. For many reasons.
First, that women should cry if unfair things happen. And that guys shouldn't, or that they don't have a reaction at all. (Hint: They do.)
Would some prefer it? Sure, but so would some guys, for the same reason. And other reasons.
Anyhow, good on Soledad for insisting on talking about the things that she wants to, instead of being pigeon-holed. In the end, I suspect her talks about actual tech are a lot more effective at raising awareness of the women-in-tech issues than talks on the subject itself would be.
