I agree, and he's slyly discouraging serious debate of his points since Facebook is so "cool". Software actually does need to be discussed. Leadership is critical in any structure of any size. The thought that every brogrammer is making decisions makes me think that he's either overstating this fact (every programmer in the world makes some decisions everyday), or that Facebook is chaotic. The rate of source code commits is fairly meaningless: with 1 shitty rushed commit, you might have to check in another 4 to fix it up. So, with 5 commits in, are you 5x more productive? Hackathons are a great way of interfering with life outside the office. There are other (possibly better) ways to give people a chance to crank out good work on side projects. Like a sabbatical where you spend a few weeks working on something you think is important. The hot tub thing makes me think Facebook is a testosterone-heavy environment.

Maybe I'm just uncool and took his flame-bait. Facebook does sound like a great place to work. But these kinds of puff pieces have a naivete that makes Facebook look like a frat house with a dark side that is not actually discussed.
