I'd like to see someone look at the mechanics of how boring, menial, repetitive grunt work is performed under this model. No doubt Valve/Gore/etc has a lot of that to do, just like any other business. And obviously it gets done. But I'm interested in how that looks up close. Does this kind of work tend to find its way to those in the company who don't have a problem rolling up their sleeves and gutting it out? And if so, do they ever end up resenting it?

In my current (traditional) workplace, you're responsible for your own grunt work, there's no pushing it off on someone else. That is enforced by management, however, and if that traditional management disappeared, I imagine the distribution of grunt work is one of the first things that would change.
