If there's one thing that illustrates how screwed up most companies are...

It seems to be an accepted fact of business life that when a new CEO gets appointed, heads always roll.
If there is one proof of how silo'd hierarchical companies create painfully counter-productive internal competition, perhaps that is it.
After all, if heads start rolling, it's usually an indication of either the new CEO seeing his exceptionally bright co-workers as threats or obstacles, or that the structure he's inheriting is fundamentally flawed.
In the first case - surely that's kind of dumb? In the second... should it really need a new CEO to sort?
And before anyone asks, no, I have no idea who/when/if a new emap CEO will be appointed. This thought was prompted by 'the outside'.
