That's great when you're hiring CEOs or product people, but I think if you're hiring a manager it's ok if his interest is more in managing than the end product.

Otherwise what happened to Google will happen to you.

eg, losing people like Sheryl Sandberg because you can't accommodate the needs of competent careerists for self advancement.

Edit: Just want to clarify that I'm not disagreeing with the original post. When you're small everyone's a product person, but you can take that idea too far.
