"Cute" it may be, but if new leadership inspires enough people to step up, want to do something great, and their path for bringing those ideas to fruition are cleared, then Yahoo can succeed.

That said, the biggest gripe I've read about Yahoo is the insane amount of middle management. If anyone (regardless of position -- an intern, an engineer, an architect) has an idea, I would hope there is a path for that idea to be evaluated and, if show potential, is allowed to come to fruition.
