Facebook popularized the idea of "move fast and break things." Move fast, by all means, and don't be paralyzed by fear of all change whatsoever, but I really didn't appreciate it when my classmates thought that by being willing to break things constantly in our group project they were showing us all their potential to be the next Mark Zuckerberg or Steve Jobs. Or when some of those classmates were hired as my team mates and brought that crap into a customer-facing service. I interviewed at Facebook and was scared by the cowboy mentality I sensed in every room and with every interviewer. I'd like the glorification of that to be balanced by, "hey here's some concrete data demonstrating they have some real issues that could clearly be addressed better."
