You're sounding a bit like "you hysterical women" "mind your tone." While I'm all for civil discourse, I certainly don't blame anyone for getting emotional or angry. And, both sides got emotional, by the way. Nobody was being calm and rational, which you could blame on Twitter.
Humor sometimes conveys the real meaning- and in this job post, it is undeniably, No Girls Allowed. Those that think "brogrammer" means anything more deep or nuanced is giving the poster a whole lot of leeway. If they wanted a more diverse (age, sex, even race) they'd convey a different culture.
This is one of those things in the Valley that I really hate (I'm a ho-grammer). The immature attitude - up there with "rockstar" postings. Is there anything in the ad about the tech? Oh right, because it's "stealth" (another annoying Valley thing). I am also wary of a company that feels the need to state that programmers get some sleep. Really? The reality is that they're going to get tons of applicants because it's a recession. The applicants are going to be eager and inexperienced, probably not from here. The poster didn't evenhave to use brogrammer to get 95% men applying- that's roughly the % of men in the CA-Bay Area industry.
The new hires are going to work for a bit, the start-up will fizzle to nothing, but in the meantime the brogrammer will learn how to party in SF, go to strip clubs, get crunk, work hungover, and write passable code. He'd doubtless leave with a few great connections, and then starting or join another startup, where he'll fondly remember the ad that got him here and post a similar one. A kid just out of a midwestern school will see it and buy a cheap one-way ticket to SF. Like begets like (another thing that annoys me about SV). The monoculture continues.
