Even in the early/mid-90s, working along side women wasn't a big deal. I learned a lot from some very capable senior female engineers while at Netscape. I even got some great advice on how to look at things like "part time work", etc. I think the bro-ness goes along side the "work hard, play hard, be at the office all hours" mentality. I've been to a few different gatherings where startups were pitching (including YC) and tune out anyone who pulls the "we are a family, we are here all hours, we blahblahblah" type thing. Liking your coworkers and developing a desire to hang out socially, etc. should develop organically instead of some "mandatory fun" type work culture.
