Surely, however, there's someone at Facebook who could skew more Jobsian on the performance side than Zuckerberg is able. Steve Jobs didn't run Apple's keynotes because he was the company's CEO; he ran them because he was the company's best presenter.

It's widely expected that Apple will host an event of its own sometime soon to unveil new products, like the next model iPhone. reports that Tim Cook will "preside over" the event. Cook has been in the public eye before--he was Apple's representative at the earlier this year and he joined Jobs on stage to field questions at last year's . But this will be his first time running the show.

Though the presenter will change, it's unlikely that Apple's presentation format will vary dramatically from the showmanship we're accustomed to. We don't yet know whether Cook will seem as comfortable as Jobs did, or skew closer to the less-polished Zuckerberg approach. Should Cook--and his audience--find that the presentation role doesn't suit him, one hopes that he'll be confident enough to delegate that task to a better option the next time around.

After all, Apple's keynotes aren't designed to showcase the greatness of their presenter, but rather the products they're presenting.
