“I’d stipulate would be that women (and other minorities), on average, have less time outside of work to participate on forums such as these, and are less willing to spend productive work time responding to questions on a public forum”
Not sure I understand the second part of this whole statement. It sounds like what are saying is that women are less likely to respond to questions on a public forum. Isn’t that the whole idea around Stackoverflow? To contribute? What am I missing?
