Have an upvote. I am curious why you decided to volunteer that. Not a criticism. Do you think it would be better if I (or someone else) asked "What's your gender?" Perhaps that's where I went wrong?
Aha, I just said that to be the odd one in all the "I'm a female" comments. There is nothing wrong with the question you asked, it's simply a survey. I guess knowing you're not the only female, in a (obvious) male dominated industry, is comforting.
