Top job, no less. For somebody who's accomplished as much as she has, it must be difficult finding worthy new challenges. The VentureBeat article on another thread states she's worth $300m. She only continues to work because she loves the challenge, clearly.
It's probably much simpler than that. You know that study where most people chose to be the top dog of a small group instead of being part of a larger group, but only a subordinate? Same goes here.
Besides, maybe she really believes she can turn the company around - who will be laughing if/when that happens?
