It's no surprise that Steve Jobs's approach to keynotes now feels like the obvious (and only?) way; Jobs's Apple inspired the same feelings with smartphones, tablets, and desktop operating systems. He's surely accustomed by now to seeing his innovations emulated.

But though the endless similarities between Zuckerberg's f8 keynote and a typical Jobs performance were obvious, equally apparent was the fact that Mark Zuckerberg is no Steve Jobs. Set aside leadership styles, inventions, and technologies: Zuckerberg simply lacks Jobs's charisma and natural stage presence. Zuckerberg's presentation style was decidedly more wooden than Jobs's ever was. There were moments where you could observe Zuckerberg recalling the next lines of his script, flubbing a word or two, and even occasionally starting the next line--and stopping himself--before finishing the preceding one.

Most assuredly, , too. But you'd never know it to watch an Apple event live: He never stumbled for a line, never seemed to need to gather his thoughts, and spoke with the same smooth, calm delivery you'd expect between friends at dinner.

I don't fault Zuckerberg for his more stilted style. Public speaking is hard; public speaking in front of massive crowds (more than 100,000 people were watching the live video stream, not to mention the in-person audience) with no notes is harder still. And I don't fault Zuckerberg for attempting to take a page out of Steve Jobs's playbook either: Apple clearly honed the craft, and was continually successful at building tremendous excitement with its presentations.
