I dunno about his assessment of Brogrammers. Engineering departments have always had a sizable Bro contingent. The typical male Stanford CS student could very well be the paragon of the programming Bro... and they are usually pretty good at what they are doing.
Maybe he's getting Brogrammers confused with web dev scenesters. Awesome Tumblrs, lo-fi keytar side band, scruffy hair, interesting glasses, polaroid cameras. I don't know if those guys have a name yet. Hipster is too easy...it's never really been "hip" to have a desk job.
