Agreed. I understand there's a hacker mentality here, but who would really pass up the CEO at an established behemoth like Yahoo to take the reigns of an unproven (or found) startup?
Me. I'm not qualified to be the CEO of Yahoo, so I would only be setting myself up for failure if I took the job. But running a smaller company limits the amount of harm I can do to myself and others while I learn the ropes.
The only reason to expect Mayer to do well as the CEO of Yahoo would be if her work at Google were similar to that job in some respect. I'm not sure it is.
