Is self-management growing, shrinking or stagnating?

As I was tossing around ideas with a friend, he asked if the number of self-managed companies was growing. After rushing to say "of course," I realized that I didn't know. We hear about companies adopting self-management, but we don't hear about the ones that fall back to command-and-control.

Have you guys looked into this at all? Have you been keeping track of the companies you've had contact with?
