First, only support Women in Technology if you want to. It’s an idea that appeals to some, but not to everyone and if it’s not your cause, that’s fine. I don’t think less of you for not supporting the cause, but I would if you bash it. There’s no reason to do that.
What is WIT? Karen Lopez has a great writeup, and one I agree with. We want to make sure people that want to get into technology can, and not feel that their interest in the field is “wrong”.
