There are successful companies out there that don't adhere to the typical structure, and I'm glad to add another company to that list. For example, the 20,000 employees at Gore-Tex have no bosses, you're on a team.

Also, Tony Hsieh sits in a cubicle among employees -- he's just one of the guys, even though he's the founder & CEO of a giant company recently purchased by Amazon. His cubicle office isn't near any windows either. He's also very approachable in the office, just as any other employee would be.
