I just tweeted you with a link to my blog because it was the only contact info in your profile. HN used to be a lot rougher. I probably have the second highest karma of any openly female member. I used to get badly raked over the coals. I think a) yeah, there is room for improvement on HN b) I have been in even worse sexist business/professional situations, so it took me a while to connect the dots and realize it was a sexism thing. So I think you probably do need a thick skin and more savvy about how to deal with such things if you are going to make it in business. This is really not that horrible, in the grand scheme of things.
Sorry you are having some trouble with it. (I would have emailed you these remarks, but, again, no ready means to do so.)
