If they had ads for themselves, I assume they had income. But they say that their platform doesn't have ads. Where did they get the money to pay their own ads?
Something I've been for a while now is why this gender disparity is so strong in this specific area of engineering compared to all other engineering areas. People seem to claim it's because of the "geek" stereotype, but that seems more like a symptom than a cause and I fail to see how it enforces this disparity, considering there's nothing preventing a woman from being a geek too.
