Great idea; it sounds like someone at Yahoo is taking Christensen's advice. This will only work well if the division is given enough autonomy. If a small division is trying to help meet the massive revenue goals of mainstream Yahoo, it's just not going to work. They're not going to get the resources or motivation that they need. That's the problem with Google's 20% time. You're not really encouraged to do little projects, something that a startup might do. Instead, you're encouraged to contribute to the bottom line of Google, which severely limits the kind of things you can work on (i.e., "do search or you're wasting your time"). This is compounded by the fact that your 20% time is inconsistently factored into your employee evaluation (for better or for worse).
