As for your point about Google, some ideas are so powerful that they fall outside the conventional expectations of business practice. The fact that Google's founders have, until lately anyway, been unassertive in the manner of Microsoft, does not indicate that Bill Gates' approach "is not worth much". Absent some ground-shaking idea like Google's, I would argue the assertive approach of Microsoft is the norm for a successful company and a key ingredient missing in the YC environment.
