I've seen several articles recently about an upcoming middle management supply crisis, meaning that things are going to get worse before they get better: Who wants to be a middle manager? - USATODAY.com.

I don't see this as being a problem where I work, but I've read about other technology companies where managers have upwards of nearly 100 direct reports (none of those reports being managers). How in the world can you really manage and develop that many people? Your duties must be exceptionally light per person or there are virtual teams that self-police themselves to make progress.
