Both of our local photo stores are staffed by an equal number of men and women, and partially owned by women. I also meet a lot of photographers in the field, and I would give women the edge there. On other photo sites my contacts are about 50/50, with the women being far more productive. I don't think they're less into gear, I think they may be less into talking about it. Honestly, I think we tend to assume that we dominate photography and we act like it, and so the places we congregate, and the way we talk about it, can be off-putting to women. I think what I'm saying is that this question is more about us than them.
