This is a common refrain I've seen on HN when this topic has come up before, but there's a problem with it. The is a huge difference between (1) "flat organizations can work" and (2) "groups make better decisions than individuals, and this disparity is even larger on complex issues."

If #2 is true shouldn't an organization like Valve run circles around every single competitor it has since they're all dinosaurs with hierarchies and Valve isn't?
